s390x/cpu_models: drop "msa5" from the TCG "max" model

Browse Source 
We don't include the "msa5" feature in the "qemu" model because it
generates a warning. The PoP states:

"The message-security-assist extension 5 requires
the secure-hash-algorithm (SHA-512) capabilities of
the message-security-assist extension 2 as a prereq-
uisite. (March, 2015)"

As SHA-512 won't be supported in the near future, let's just drop the
feature from the "max" model. This avoids the warning and allows us for
making the "max" model match the "qemu" model (except for compat
machines). We don't lose much, as we only implement the function stubs
for MSA, excluding any real subfunctions.
