Fix bug 1264952 (Adjust perfschema autosizing for Percona Server
mutexes).

Testcase sizing_growth checks the performance schema autosizing
heuristics by performing some actions on the server and counting the
resulting PFS records. One of such tests, count of mutexes per
connection, behaves differently on Percona Server, because a
connection hits one extra mutex. This failed the sizing_growth
checks, which were then recorded as expected result on the initial PS
5.6 port.

Fix by expecting four mutexes per connection in sizing_growth,
tweaking heuristics constant mutex_per_connection in pfs_autosize.cc
to match, and re-recording sizing_default, sizing_high, sizing_low,
and sizing_med testcases.
