Remove the benchmark part of the selftest. It uses the undocumented

OPENSSL_rdtsc() routine to get a high-precision timestamp, and (although
this is the only user of this routine in libcrypto) forces every platform
willing to provide fast assembly versions of some routines, to also
provide OPENSSL_rdtsc().
