install-deps: remove the legacy resolver flags

This was a workaround that was introduced long time ago. This will be
something that could be deprectaed at some point [1]. And its preventing some of the dependencies to be
downloaded or stored into the wheelhouse. Deps like jsonschema, parse,
mypy, cryptography etc.
