fstab-generator: rename 'post' variable

Originally (6b1dc2bd3cdb3bd932b0692be636ddd2879edb92) we had 'pre' and 'post'
to refer to remote-fs-pre.target and remote-fs.target or local-fs-pre.target
and local-fs.target. But 'pre' is long gone, and 'post' by itself doesn't
make much sense. Rename it for clarity.
