Uniformize ifdefs to ECDSA_C+ECP_RESTARTABLE
Some parts were already implicitly using this as the two ifdefs were nested,
and some others didn't, which resulted in compile errors in some configs. This
fixes those errors and saves a bit of code+RAM that was previously wasted when
ECP_RESTARTABLE was defined but ECDSA_C wasn't
