PHPC-2135: Test with consistent version of crypt_shared

Use the crypt_shared library provisioned by download-mongodb.sh and add an additional task to disable the library and fall back to mongocryptd.

This also revises how we pass environment variables into run-tests.sh and the test suite. Everything is now explicitly passed instead of relying on export attributes from a parent context.
