Guix system users need to use guix shell and the provided
scripts/manifest.scm to do local builds and testing.

However 'guix shell --container' doesn't have /usr/bin/env, so tests
don't work if we rely on what is in the sheebang (#!).

In various Makefile.am we had:
    PY_LOG_COMPILER = $(PYTHON)
but PYTHON was undefined, so for some reasons that made 'make check'
rely on the sheebang instead of just using 'python'.

With this fix, with
'guix shell --pure --container -f scripts/manifest.scm',
./configure now properly detect the 'python3' that is in the path:
    Interpreters paths:

      PYTHON3..................: python3

And 'python3' is then used to run the python test scripts, which makes
then makes 'make check' succeed.

In configure.ac we already build xz, bzip2 and gzip archives as we
have the following:
    AM_INIT_AUTOMAKE([dist-bzip2 dist-xz subdir-objects])
and that in the commit aedf4ffd7d16721b522df2d20b1f41f8574c3940 ("Add
tests for builds using tarballs") we automatically built these
archives during make check.

But we forgot to add the required utilities in scripts/manifest.scm.

Without tar and xz, when running make check with
'guix shell --pure --container -f scripts/manifest.scm', we have the
following error:
    tardir=libsamsung-ipc-0.7.0 && ${TAR-tar} chof - "$tardir" | \
            XZ_OPT=${XZ_OPT--e} xz -c >libsamsung-ipc-0.7.0.tar.xz
    /bin/sh: line 1: xz: command not found
    /bin/sh: line 1: tar: command not found

And if we don't add bzip2 we still have the following error:
'guix shell --pure --container -f scripts/manifest.scm', we have the
following error:
    tardir=libsamsung-ipc-0.7.0 && ${TAR-tar} chof - "$tardir" | \
          BZIP2=${BZIP2--9} bzip2 -c >libsamsung-ipc-0.7.0.tar.bz2
    /bin/sh: line 1: bzip2: command not found

And we also need gzip:
    tardir=libsamsung-ipc-0.7.0 && ${TAR-tar} chof - "$tardir" | \
            eval GZIP= gzip --best -c >libsamsung-ipc-0.7.0.tar.gz
    /bin/sh: line 1: gzip: command not found

Without that fix, when running ./configure with
'guix shell --pure --container -f scripts/manifest.scm', we have the
following error:
    checking for libcurl >= 7.62.0... no

    configure: error: Package requirements (libcurl >= 7.62.0) were
    not met:

    No package 'libcurl' found

    Consider adjusting the PKG_CONFIG_PATH environment variable if you
    installed software in a non-standard prefix.

    Alternatively, you may set the environment variables
    LIBCURL_CFLAGS and LIBCURL_LIBS to avoid the need to call
    pkg-config.  See the pkg-config man page for more details.

This issue wasn't found before because builds in guix shell weren't
often tested with --container.
