Chroot builds: Provide world-readable /nix/store 

This was causing NixOS VM tests to fail mysteriously since
5ce50cd99e740d0d0f18c30327ae687be9356553. Nscd could (sometimes) no
longer read /etc/hosts:

open("/etc/hosts", O_RDONLY|O_CLOEXEC) = -1 EACCES (Permission denied)

Probably there was some wacky interaction between the guest kernel and
the 9pfs implementation in QEMU.
