Fix up certificate error reporting histograms

This CL adds a failure histogram for certificate error reporting,
similar to the histograms we have for Expect CT and HPKP reports.

It also negates the net error codes for Expect CT and HPKP histograms,
to match up with the histogram enums. (See  bug 616599 .)
