petscsys.h: find memcpy and memset in string.h

C89 and later say that memcpy and memset are in string.h. With glibc,
memory.h merely includes string.h, and one user reported an error due to
undefined memset (which I cannot reproduce). So quit bothering with
nonstandard memory.h and just include string.h.
