Remove unused VS2015 realloc heap mismatch suppression.

Remove unused VS2015 realloc heap mismatch suppression.

The suppression was never hit on the bots, and I cannot reproduce it
locally even running Dr. Memory builds prior to the several VS2015 fixes.
If with the latest Dr. Memory it happens again in some environments, we
would prefer to address it at the Dr. Memory level rather than with a
Chromium suppression as it is general enough to affect external users.
