build/Makefile.common.inc: unset OSMO_REPOSITORY

Don't have a default value for OSMO_REPOSITORY, as this leads to manuals
getting uploaded to the wrong directory (publish) target and installed
to the wrong directory (install, uninstall).

Add checks to ensure the variable is set before using it in install and
uninstall.
