kernel32-K32GetPerformanceInfo: Remove patch set.

As of 8622eb326fb, SystemProcessInformation should now actually be reasonably
fast, requiring only a couple of server calls. This patch set would make
K32GetPerformanceInfo() even faster, but without any record of what it helps,
it's not particularly likely that it's making a significant difference anymore.
