perf tools: Add compression id into 'struct kmod_path'
Store a decompression ID in 'struct kmod_path', so it can be later
stored in 'struct dso'.
Switch 'struct kmod_path's 'comp' from 'bool' to 'int' to return the
compressions array index. Add 0 index item into compressions array, so
that the comp usage stays as it was: 0 - no compression, != 0
compression index.
Update the kmod_path tests.
Committer notes:
Use a designated initializer + terminating comma, e.g. { .fmt = NULL, }, to fix
the build in several distros:
