Subject: [PATCH] chromium: honor systemdSupport

This commit exposes that support for compilation without systemd,
controlled by the global systemdSupport argument.  This argument is
understood by many other nixpkgs expressions and can be set globally
in ~/.config/nixpkgs/config.nix.

(cherry picked from commit 5f9ce130b2f99f6cc818428913b1929519757089)
