The install rule for TEST_GEN_MODS_DIR copies *.ko from the directory with rsync which fails if there are no modules, for example because the directory's Makefile skipped building them. Only run rsync if there is something to install. This currently affects the livepatch suite but it seems sensible to fix here for added robstness.
