Makefile: matterbridge.tar.xz: fix various issues

- Files in the Guix store are read-only, And the tarball
  has to get write permissions to be updated, however a
  typo made the +w become +x.
- To update the tarball, we need it to be uncompressed. So
  we do uncompress it to add the service file, but that can
  fail if there is an existing matterbridge.tar already there.
  So we simply rm matterbridge.tar to fix it.
  Not using compressed tarballs as inputs have the side effect
  of increasing the store size as each different builds of
  matterbridge.tar.xz is stored in the store.
- A whitespace issue was fixed.
