bash-completion: use POSIX character classes in regular expressions

Browse source 
bash uses POSIX extended regular expressions via regex(3), which does
not guarantee support for shorthand character classes. Although glibc
supports it, msys2-runtime does not.

Make sure the completion script works (hopefully) everywhere by being
more portable.

Fixes: https://github.com/msys2/MSYS2-packages/pull/1549
