  Stop calling gc.collect in the Python incrgc.

@jimfulton and I have talked about it, and I'm (mostly :) convinced that
this shouldn't be an actual problem for any of the reasons described in
the previous comment.

If I use PyPy 5.4.1 to run the ZODB master test suite against
this (well, with #44 rolled back) I don't get any unexpected
failures. (I haven't run the ZEO test suite yet.) Which honestly amazes
me because I'm sure I used to get test failures---I guess the PyPy GC
has changed...which means we may see some failures on Travis. I'll try
to set up an older PyPy to verify.
