booster: Move fstab parsing into booster from libglusterfstag-release-2.0

This is another attempt at fixing build problems on Solaris.
I am told that booster build is disabled on Solaris and I know
that it is disabled on Mac OS X also. Getting it to work
on both these systems is now on my TODO list, mainly
because on both these systems, we can have a glusterfs client
running without requiring FUSE.
