[PW_SID:665727] [1/2] handshake: add support to work around buggy OWE APs

[IWDTestBot]

The early OWE implementation for hostapd always used SHA256 to calculate
the PTK, which violates the spec for group 20 and 21. This bug was in
there long enough for the bug to make it into products and now it must
be worked around here.

If the workaround flag is set, always use SHA256 to calculate the PTK.
