Don't assume sysbox-fs FUSE dir is at /var/lib/sysboxfs.

The location of the sysbox-fs FUSE dir is configurable
via the sysbox-fs command line. Thus, do not assume
it's under the default location ("/var/lib/sysboxfs")
and instead let sysbox-fs determine its location.

Related to sysbox issue #310.
