In commit fd29a61f01 ("package/ejabberd:
bump version to 23.04"), the EJJABERD_SOURCE variable was changed to
"ejabberd-$(EJABBERD_VERSION).tar.gz", which is the default value for
the _SOURCE variable, causing check-package to complain. Fix that by
dropping the useless variable definition.
Fixes:
package/ejabberd/ejabberd.mk:8: remove default value of _SOURCE variable (http://nightly.buildroot.org/#generic-package-reference)
