Performance schema heuristics need to be updated

[Philip Stoev]

the perfschema.sizing_growth MTR test fails as follows:

This implies that codership-galera takes more mutexes per connection compared to stock mysql. The test has the following comment:

#
# IMPORTANT NOTE:
# when any measurement here changes, the heuristics
# in storage/perfschema/pfs_autosize.cc need to be updated.
# Note that this in turns will lead to different estimations for automated
# sizing, and imply to update the results for sizing_*.

I have added the problematic test to the disabled.def
