Use entry 0 of the GPU.BlacklistTestResultsPerEntry to keep total count.

Every time we record entries in the GPU.BlacklistTestResultsPerEntry histogram,
increment the zero'th entry. This will provide a total count for the number of
times we've recorded data in the histogram and a convenient denominator to compute
blacklist percentages per entry.
