[LTP] [PATCH] lib/tst_test: Fix FS kernel supported check

[Cyril Hrubis]

In case that there is only single filesystem defined in
tst_test.filesystems we format the device in the setup rather in the
function that iterates over all filesystems. However we missed a check
if a filesystem is supported in this shortcut, hence if mkfs for the
filesystem was installed and kernel support was missing the test failed
when it attempted to mount the filesystem.
