[PATCH] buildchroot: Correctly mount /proc

[Alexander Smirnov <asmirnov@ilbers.de>]

The variable IMAGE_ROOTFS doesn't provide correct path, so the
BUILDCHROOT_DIR should be used instead.

This patch also fixes the issue when after building the following target:

 multiconfig:qemuarm-wheezy:isar-image-base

the folder:

  tmp/work/debian-wheezy-armhf/buildchroot/rootfs/run/shm

stays mounted. This issue is caused by initscripts.postinst script. During
execution this script performs check whether it's running under chroot
environment using ischroot command (it checks for chroot via proc). So chroot
is not found and initscripts.postinst continues setup like for host.
