certs: Fix build error when CONFIG_MODULE_SIG_KEY is empty
Since b8c96a6b466c ("certs: simplify $(srctree)/ handling and remove
config_filename macro"), when CONFIG_MODULE_SIG_KEY is empty,
signing_key.x509 fails to build:
CERT certs/signing_key.x509
Usage: extract-cert <source> <dest>
make[1]: *** [certs/Makefile:78: certs/signing_key.x509] Error 2
make: *** [Makefile:1831: certs] Error 2
Pass "" to the first argument of extract-cert to fix the build error.
