Bug description

If a mod_invites Link is browsed via the web browser, a crash occurs and my nginx proxy throws an upstream error. After some investigation, it turned out that the directory priv/mod_invites was not installed to my system via "make install".

A manual cp -r priv/mod_invites /usr/lib/ejabberd-26.01/priv/ fixed the issue.
Probably the Makefile needs some updates.
