Fix OCF files installation in devel/upload
Fix OCF files installation in devel/upload

LIBDIR was not defined, so the files ended up directly under /, not
good. Now they're properly installed under /usr/lib/ocf, as per
http://linux-ha.org/wiki/OCF_Resource_Agents.

Also add "set -u" to prevent future occurrences of this kind of bug.
