Add file exclusion to trunk patch creation in push-to-trunk.

Add file exclusion to trunk patch creation in push-to-trunk.

This is another step towards getting rid of the bleeding edge change log file. Now it can be omitted in a follow up CL.

I hope this approach has no potential for omitting any required files. I could
not find an innate "exclude" feature in git diff.

lgtm, although I am not sure how the change to GitDiff relates to the change in
the test.

The change in the code will cause two calls to git instead of one. The first is
(in the context of the test):

git diff --name-only svn/trunk hash1

to get the list of changed files - the test driver will make it return
"file1\nfile2\n" after which git is expected to execute again like this:

git diff svn/trunk hash1 file1 file2
