drbd-utils: add submodule drbd-headers into SRC_URI

1. add submodule drbd-headers into SRC_URI

   drbd-headers is git submodule of drbd-utils, so drbd-headers's
code will not fetch during do_fetch. but it will get during
do_compile(there is a logic in drbd-utils's makefile to do this),
but if during do_compile, network is broken,  fetch drbd-headers
will fail, then do_compile will fail since missing header file.

2. add patch for fix drbd init script
