[LTP] [PATCH] ftruncate04: require CONFIG_MANDATORY_FILE_LOCKING=y

[Jan Stancek]

commit f7e33bdbd6d1 ("fs: remove mandatory file locking support")
removed mandatory file locking support, but mount option
is still allowed and produces no error. There's a warning
in dmesg but it's pr_warn_once() so we can't rely to always
find it there.

Make the test check also for CONFIG_MANDATORY_FILE_LOCKING=y.
