This is just a copy of the current inputrc from the "filesystem" package
which currently gets installed as ~/.inputrc on the first start.
The goal is to remove ~/.inputrc, so that on the first msys2 start the config
is already there and a shell restart is no longer needed.
readline is statically linked into bash, so there is no readline dependency,
so we assume that libreadline is installed with "base" in some way.
