Revert "Check for static initializers on linux-chromeos-rel." again.

This is a manual revert of https://crrev.com/810169. The
linux-chromeos-rel trybots have Clang code coverage enabled. This
causes the static initializers check to generate false positives [1] in
some cases. Since there is no proper immediate solution, stop running
the static initializers check to get it out of the way of landing CLs.
