Fix fw_filesystem.sh to run in an automated environment under busybox.
After this change, fw_run_tests.sh still fails at some point in fw_fallback.sh, with error "usermode helper disabled so ignoring test". This is coming from fw_lib.sh:verify_reqs() because $HAS_FW_LOADER_USER_HELPER is set to no.
Dan Rue (2): selftests: firmware: remove use of non-standard diff -Z option selftests: firmware: add CONFIG_FW_LOADER_USER_HELPER_FALLBACK to config
