Fix installation of libgbm-dev package in install-build-deps.sh

crrev.com/106633002 has recently introduced a dependency on libgbm-dev.
Unfortunatelly, this package is a bit more trickier to install, for the
following reason: it depends on mesa-glx and, conversely to most of the
other packages, only one version of mesa (w.r.t backports) can exist in
the system. Google's workstations are configured to use the -lts-saucy
version of mesa. The right package in this case is libgbm-dev-lts-saucy
and attempting to install just libgbm-dev ends up in a failure.
This change fixes install-build-deps.sh, installing the matching version
of libgbm-dev (w.r.t libgl1-mesa-glx), falling back to libgbm-dev.
