Fix 'too many levels of symbolic links' error.
In an Ubuntu Precise chroot on the Chromebook Pixel, /run/shm is a
symbolic link to /dev/shm, so bind-mounting /run/shm to /dev/shm
is really bind-mounting /dev/shm to itself, which causes a 'too many
levels of symbolic links' error. To fix this, we check for a symbolic
link prior to running this command.
BUG=none
TEST=cros_sdk no longer prints errors on Chromebook Pixel
