[PATCH 5/5] check-parallel: allow FSTYP selection from the CLI

[Dave Chinner <david@fromorbit.com>]

From: Dave Chinner <dchinner@redhat.com>

Add a CLI option to specify the initial FSTYP to test. If this is
not specified the the default of "xfs" will be used. This option is
different to the way check has FSTYP specified as check-parallel
has no infrastructure to support non block device based filesystems
and hence we have to reject virtual or network based filesysetms
are this point in time.

This patch only implements default mkfs parameter support for the
test device. Config sections can be used to override this as check
will then format the test device when the section that defines
non-default test device mkfs options is selected.
