move calls to cstdlib::getenv to env::getEnv

Wrapped the cstdlib::getenv() call into env::getEnv
so that it can be tested by mocking the env namespace,
by just dropping in test_env.cpp which implements those
methods and tying them a singleton upon which we can set
expectations.

Note: regardless of the approach taken to mock this, wrapping
this method is a good fix.
