[LTP] [PATCH 3/3] ima_setup.sh: Use tst_supported_fs instead of df

[Petr Vorel]

Hi all,

[ Cc linux-integrity ML ]

Cyril, thanks a lot for your review, patchset merged.

@linux-integrity Last 7 fixes made IMA working on my setup, if anything broken
please speak up, so that we can fix it before LTP release (git freeze is going
to be very soon, likely this week).

Kind regards,
Petr
