certs: fix and refactor CONFIG_SYSTEM_BLACKLIST_HASH_LIST build
Commit addf466389d9 ("certs: Check that builtin blacklist hashes are valid") was applied 8 months after the submission. In the meantime, the base code had been removed by commit b8c96a6b466c ("certs: simplify $(srctree)/ handling and remove config_filename macro"). Fix the Makefile. Create a local copy of $(CONFIG_SYSTEM_BLACKLIST_HASH_LIST). It is included from certs/blacklist_hashes.c and also works as a timestamp. Send error messages from check-blacklist-hashes.awk to stderr instead of stdout.
