grep-cli: support files compressed by compress(1)

Browse Source 
While Linux distributions (at least Arch Linux, RHEL, Debian) do not support
compressing files with compress(1), macOS & AIX do (the utility is part of
POSIX). Additionally, gzip is able to uncompress such compressed files and
provides an `uncompress` binary.

Closes #1547
