Ignore environment changes in CI

The test suite needs to ignore any changes to the environment because loading MKL's shared library on some platforms (such as Windows) can create environment variables for OpenMP (e.g. __KMP_REGISTERED_LIB_<PID>) that live the entire Julia session and make the environment appear modified. Fixes JuliaLinearAlgebra#130
