net-im/ejabberd: add 22.05

Fix bashism in OpenRC init script. Drop support for logrotate in favor
of ejabberd's built-in log rotation mechanism.

Also depend on >=acct-user/ejabberd-1, which will create the ejabberd
with HOME set to /var/lib/ejabberd, i.e., ejabberd's spool
directory. This allows us to drop ${PN}-19.08-ejabberdctl.patch.
