dev-util/bazel: pull latest upstream revision.

This CL applies the Gentoo patch
https://github.com/gentoo/gentoo/commit/554a3365c8a6807a02976a55462a9708638457e2
which was developed in collaboration with Chromium OS engineers to make
Bazel compilation respect Portage build flags.

This is a necessary step towards compiling Bazel with Clang.

This CL differs from the upstream patch in a small and typical way;
patchset 1 is the exact state of Gentoo's ebuild for reference.

TEST=`sudo emerge bazel`
BUG=chromium:979911
