ssl_ciphersuite: remove SHA256 "mid" options

In our ciphersuite simulations and known information about all the
statistically-significant browsers, anything currently negotiating
these SHA256 options will fall back to the equivalent SHA1 options
that remain.  There's no functional security difference between
the two as HMACs (and SHA1 is slightly faster, not that it will
matter much in practice).  This further shortens the list of bad
ciphers that we only support for compatibility reasons, and thus
further reduces the line noise in looking at cipher stats and
such.
