Fix false dep mismatch for /usr/bin/env

I'm seeing RPM build jobs in RelEng Jenkins fail with a dep mismatch, calling out `/usr/bin/env`.

I didn't see this in my sandbox runs yesterday, so I suspect it only happens in RelEng. Not sure why there would be this difference between the two however. Could also be related to lots of recent infra changes that are happening as we move to new cloud provider.

Also the sandbox is currently down because Rackspace (old provider) infra can't spawn VMs. Need to figure out how to work with the new prototype sandbox on new cloud provider to get an env for testing.
