Development script for testing changes locally.

Several ebuilds depend on vboot_reference, either by checking out the
vboot_reference repo and building it or by using the installed libs
during build time. To simplify catching problems in other ebuilds
while changing code in vboot_reference, this patch adds a new script
that tries to emerge all the affected ebuilds.

BUG=None
BRANCH=None
TEST=`../platform/vboot_reference/emerge_test.sh` inside and outside the chroot
