USN-1045-1 fixed vulnerabilities in FUSE. This update to util-linux adds
support for new options required by the FUSE update.

Original advisory details:

It was discovered that FUSE could be tricked into incorrectly updating the
mtab file when mounting filesystems. A local attacker, with access to use
FUSE, could unmount arbitrary locations, leading to a denial of service.
