Subject: [PATCH] Make dracut-squash a weak dep

The dracut module is opportunistic about using the built-in squashfs
support only when available, but the spec file hard requires it. Demote
it to a weak dep to truly make it optional.

This caters to environments which strive to stay minimal, like FCOS and
RHCOS. See https://github.com/coreos/fedora-coreos-config/pull/708 for
details.
