Suppress readability/inheritance check for cpplint.py for now.
Suppress readability/inheritance check for cpplint.py for now.

This check never triggered before, since cpplint.py was looking for
override not OVERRIDE. Since Chromium prefers override now, the
linter is now (correctly) warning. However, the old Chromium convention
(and the one implemented by the clang plugin) is to explicitly annotate
all overrides with both virtual and override. The clang plugin code has
been updated, but new binaries have not yet been built. Until clang
rolls, suppress the warning.
