[Buildroot] [git commit] nano: fix build breakage with libmagic

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=893108810b952777feca054a90c7ecfe7cad06e1
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

As reported by Cassiano Martin in bug #6692 if host == target the nano
package can pick up the host libmagic and break.
So add a check to see if the file package is enabled and use it,
otherwise just disable libmagic support.
