Rollback of commit 96d4628.

*** Reason for rollback ***

Broke installation on latest release.

Fixes bazelbuild#1846

*** Original change description ***


Reintroduce .bazelrc and set --action_env defaults

Shipping a .bazelrc was removed in 009b48b.
However, as per our "Specifying environment variables for actions" design
document, we want to ship a global rc file specifying the common environment
variables to be inherited. So revert that change and add the desired entries
to the global bazelrc file we're shipping.
