fstests: get rid of set_prog_path

It's just a one line wrapper that adds complexity, remove it. Move
the couple of calls in tests to common/config, but leave the xfsdump
setup in place and just convert it.

[Eryu: add the missing CHECKBASHISMS_PROG definition, define
mkfs.btrfs and mkfs.f2fs with set_mkfs_prog_path_with_opts]
