[Buildroot] [PATCH v4 6/6] polkit-rules-test-initd: new test

From: Adam Duskett <Aduskett at gmail.com>

This test is a simple integration test of the polkit package on systems
not running systemd.

It consists of the following:
- A simple hello world c application that outputs "Hello polkit!" is compiled
  and installed to $(TARGET_DIR)/usr/bin/

- The brtest user attempts to run "pkexec hello-polkit" and is denied.

- A hello-polkit.rules file provided by polkit-rules-test-initd
  is copied from /root/ to /etc/polkit-1/rules.d

- The brtest user attempts to run "pkexec hello-polkit" and should not succeed
  with the output "Hello polkit!"
