[Buildroot] [PATCH] Add package linux-pam

[Dmitry <golubovsky@gmail.com>]

1. Add the linux-pam package building instructions
2. If the linux-pam package is selected, make sure it builds before
   busybox just in case busybox is configured with PAM support
   (make linux-pam a dependency of busybox)
