Subject: [PATCH] policycoreutils: run_init: define _GNU_SOURCE

Trying to compile run_init with musl will fail with:
run_init.c: In function 'authenticate_via_shadow_passwd':
run_init.c:206:40: error: implicit declaration of function 'getpass' [-Wimplicit-function-declaration]
  206 |         if (!(unencrypted_password_s = getpass(PASSWORD_PROMPT))) {

This is because getpass in musl is guarded only for _GNU_SOURCE, so
define _GNU_SOURCE for run_init.
