Bug 1290957 - ensure MOZ_AUTOMATION builds require a cargo with --frozen support; r=chmanchester

Browse Source 
We want to ensure that our automation builds don't pull in libraries
from crates.io, and we need --frozen support in cargo to do that.  If we
don't have that support, we shouldn't build.
