libmount: use mount(2) for remount on Linux < 5.14

It seems mount_setattr() is supported on Linux < 5.14, but it's without
MOUNT_ATTR_NOSYMFOLLOW. That's problem for remount where we reset all
VFS flags.

The most simple (but not elegant) is to check for kernel version and
fallback to mount(2) on remount.
