Skip MapAnonymousFailNullError on host

This test relies on the system's mmap_min_addr configuration being high
enough that the test's mmap will fail. However, some hosts may set this
to a value which allows for all possible values to be successfully
mapped, breaking the test. Therefore, skip on host.

Test: test.py --gtest --host
