util: do not use mount-utils.IsLikelyNotMountPoint anymore

Browse Source 
`IsLikelyNotMountPoint()` is an optimized version for `IsMountPoint()`
which can not detect all type of mounts (anymore). The slower
`IsMountPoint()` is more safe to use. This can cause a slight
performance regression in the case there are many mountpoints on the
system, but correctness is more important than speed while mounting.
