ci/deps: drop unnecessary mappings and add Inline

The automatic mapping can work for more packages, so redundant
entries in $non_auto are just clutter.

Unfortunately, `Inline::C' is part of `Inline' on CentOS 7.x and
OpenBSD 7.3, so we'll add $non_auto mappings for those.

We'll also depend on `IO::Compress' to simplify mappings since
that's the CPAN distribution which holds both IO::Compress::Gzip
and IO::Compress::Gunzip and I'm not aware of any packagers who
split them.
