perf tools: Add support to read build id from compressed elf
Adding support to decompress file before reading build id.
Adding filename__read_build_id and change its current versions to
read_build_id.
Shutting down stderr output of perf list in the shell test:
82: Check open filename arg using perf trace + vfs_getname : Ok
because with decompression code in the place we the
filename__read_build_id function is more verbose in case
of error and the test did not account for that.
