Remove Coverity script.

Chromium has decided to drop Coverity so
we don't have any reason for maintaining this code.

Personally, I think that from a quality perspective other tools,
like all the new compiler warnings that are constantly being added
to the Clang compiler is a better way to address dangers in the code.
The maintenance cost and overhead of such advanced tools like Coverity
is simply too high.
