creator.py: include dmsquash-live-ntfs by default

Add dmsquash-live-ntfs to the default dracut modules in livecd builds.

The omission of this is probably why:

  https://bugzilla.redhat.com/show_bug.cgi?id=1449410

didn't work out as intended (I suspect it was closed unfixed).

Without this, initramfs winds up with the ntfs-3g tools lying
around, but no hooks cause them to actually get used.

AFAICT, this is a legit bugfix, not a "proposed enhancement"
so to speak.  To test that this actually fixed the problem (well,
/a/ problem, at least), I used some scripts:
