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The filenames in docs/keep_data_small.txt are a little bit outdated.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
(since commit 774bce8e8ba1e424c953e8f13aee8f0778c8a911)
libbb/messages.c -> libbb/ptr_to_globals.c
(since commit 574f2f43948bb21d6e4187936ba5a5afccba25f6)
