lib/string: remove unnecessary #undefs
A few architecture specific string.h functions used to be implemented in
terms of preprocessor defines to the corresponding compiler builtins.
Since this is no longer the case, remove unused #undefs.
Only memcmp is still defined in terms of builtins for a few arches.
