Subject: [PATCH] KEYS: asymmetric: Fix build errors as symbol undefined

pkcs7_supply_detached_data is called by x509_key_parser module, but not exported:
    ERROR: modpost: "pkcs7_supply_detached_data" [crypto/asymmetric_keys/x509_key_parser.ko] undefined!

Fixes: cfc411e7fff3 ("Move certificate handling to its own directory")
