Update install_build_deps.sh for Ubuntu Trusty.

Aside from accepting the new lsb distro name that only
changes needed were to the arm cross compile packages
list.  This was reduced a minimal set.  Also gcc-multilib
in Trust conflicts with the arm cross compiler so we
use gcc-4.8-multilib here instead.
