LOG: compiler-rt: test: Use the host instead of the target to select %expect_crash.

When running tests in a cross-compiled build, %expect_crash is
run on the host, not the target, so we need to check the host
OS. config.host_os surprisingly refers to the target OS because it
is derived from CMAKE_SYSTEM_NAME which specifies the target. See:
https://cmake.org/cmake/help/latest/variable/CMAKE_SYSTEM_NAME.html
