install-build-deps.sh has --dont-install and --platform options.

All docker files do not call isntall-build-deps.sh. Instead, cmake passes
REQUIREDPKGS to Dockerfiles, which is derived from the output of
./scripts/install-build-deps.sh --dont-install --platform PLATFORM.
This change enables caching package installaion during docker build.
