storage: Rework virStorageBackendFileSystemMountCmd 

Let's create helpers for each style of command line created. This
primarily is easier on the eyes rather than the large multi line
if-then-else-else clause used, but may also be useful if in the
future any particular pool needs to add to the command line based
on pool xml format.
