tests: (lsfd) refine the pattern for comparing the output of the commands

When comparing the output of lsfd and findmnt commands, I passed just
"$MNTID" to grep for filtering the output of findmnt. It was too relaxed.

It should be "$MNTID\b"; a space after $MNTID was needed.

shows the output triggering the bug of the test case.
