fix unintended linking dependency of pthread_key_create on __synccall
commit 84d061d5a31c9c773e29e1e2b1ffe8cb9557bc58 attempted to do this already, but omitted from pthread_key_create.c the weak definition of __pthread_key_delete_synccall, so that the definition provided by pthread_key_delete.c was always pulled in. based on patch by Markus Wichmann, but with a weak alias rather than weak reference for consistency/policy about dependence on tooling features.
