There is a known bug running clone with the CLONE_VM flag, so for host create an empty test. Change the expected output of the stdio test for a glibc difference. Change the pause test to use ScopedSignalHandler to setup/restore the SIGALRM handler. After this, running bionic-unit-tests-glibc passes for all tests.
