test_firmware: enable custom fallback testing on limited kernel configs
When a kernel is not built with: CONFIG_HAS_FW_LOADER_USER_HELPER_FALLBACK=y We don't currently enable testing fw_fallback.sh. For kernels that still enable the fallback mechanism, its possible to use the async request firmware API call request_firmware_nowait() using the custom interface to use the fallback mechanism, so we should be able to test this but we currently cannot. We can enable testing without CONFIG_HAS_FW_LOADER_USER_HELPER_FALLBACK=y by relying on /proc/config.gz (CONFIG_IKCONFIG_PROC), if present. If you don't have this we'll have no option but to rely on old heuristics for now. We stuff the new kconfig_has() helper into our shared library as we'll later expando on its use elsewhere.
