modsign: Use if_changed rule for extracting cert from module signing key
We couldn't use if_changed for this before, because it didn't live in the kernel/ directory so we couldn't add it to $(targets). It was easier just to leave it as it was. Now it's in the certs/ directory we can use if_changed, the same as we do for the trusted certificate list. Aside from making things consistent, this means we don't need to depend explicitly on the include/config/module/sig/key.h file. And we also get to automatically do the right thing and re-extract the cert if the user does odd things like using a relative filename and then playing silly buggers with adding/removing that file in both the source and object trees. We always favour the one in the object tree if it exists, and now we'll correctly re-extract the cert when it changes. Previously we'd *only* re-extract the cert if the config option changed, even if the actual file we're using did change.
