All tests fail due to input map

[bgranzow]

On cee machines, a fresh build following the steps

cd lgrtk-build
cp configs/cee_lan archie_config
./archie update

results in failures for all lgrtk tests at the initial reading of the input map with the message:

InputMap should never actually be copied!

I've tried reverting this commit in Omega_h since it's the only thing recently changed in Omega_h::InputMap, but that didn't resolve the issue.

A stack trace for one of the tests is posted below:
