It makes little sense for fsmount() to output the warning message when
mount_too_revealing() is violated to kmsg. Instead, the warning should
be output (with a "VFS" prefix) to the fscontext log. In addition,
include the same log message for mount_too_revealing() when doing a
regular mount for consistency.
With the newest fsopen()-based mount(8) from util-linux, the error
messages now look like
# mount -t proc proc /tmp
mount: /tmp: fsmount() failed: VFS: Mount too revealing.
dmesg(1) may have more information after failed mount system call.
which could finally result in mount_too_revealing() errors being easier
for users to detect and understand.

However, the default logging of errorfc will always prefix the message with the filesystem name. So, add some *fcp() wrappers that allow for custom prefixes to be used when emitting information to the fscontext log.
