compiler: Add --blacklist-filter "regex" flag to iorap.cmd.compiler

If the --blacklist-filter is specified, its regular expression is used
to ignore any file paths that are matched by regex_search.

For example,
  --blacklist-filter "[.]art$"
would remove any files with the .art extension from the output file.

Bug: 150640692
Test: iorapd-host-tests --gtest_filter='*Compiler*
