Update .gitignore pattern for "results" files.

The previous pattern was ignoring some recently added files:
    site_utils/bootperf-bin/resultsdir.py
    site_utils/bootperf-bin/resultset.py

This update the pattern not to ignore those files.  Hopefully, it
will continue to ignore other files that it should.

BUG=None
TEST=git status with changes the files that shouldn't be ignored
