utils/check-package: check files in board/

When a SysV init script is inside package/ it doesn't need to be
executable. However, when an init script is inside a fs_overlay, it
*does* need to be executable. Therefore, skip the NotExecutable test for
init scripts. We detect them based on the directory /etc/init.d
