Instead of registering the crc32-$arch and crc32c-$arch algorithms if the arch-specific code was built, only register them when that code was built *and* is not falling back to the base implementation at runtime. This avoids confusing users like btrfs which checks the shash driver name to determine whether it is crc32c-generic. (It would also make sense to change btrfs to test the crc32_optimization flags itself, so that it doesn't have to use the weird hack of parsing the driver name. This change still makes sense either way though.)
