docs: Update filenames in keep_data_small.txt
...
The filenames in docs/keep_data_small.txt are a little bit outdated.
It's better to change it to the current name.
decompress_unzip.c -> decompress_gunzip.c

update seamless uncompression code
...
This change makes "tar tf hello_world.txz" work without
adding special-casing for ".txz" extension. It also removes
ever-growing magic checking code in rpm2cpio and get_header_tar -
we reuse one which lives in setup_unzip_on_fd.
