Also set MEKE_IC_override_must_have_MEKE=False for hybrid runs, so there won't be any issues with using a reference case that had MEKE turned off. This should be merged after NCAR/MOM6#470 (and .gitmodules should be updated to point to a MOM6 tag that includes code from that PR).

Fixes #310

The ERI test runs three segments, one branch, one startup, and one hybrid; the hybrid is not bit-for-bit because MEKE is being initialized from the reference case now. It looks like there is no namelist comparison for the hybrid segment, otherwise there would be two NLCOMP failures as well.
