Do not test "make depend" for out-of-tree builds

The make/mkdep script does not understand the concept of generated
source files (like lib/dns/dnstap.pb-c.c), which prevents it from
working correctly for out-of-tree builds.  As "make depend" is not
required for building BIND and the "depend" make target was removed
altogether in the development branch, just prevent the "make depend"
check from being performed for out-of-tree builds in GitLab CI instead
of trying to add support for handling generated source files to
make/mkdep.
