detect.py: replace compile_and_run with compile_and_forget

This function is only used in setup.py to detect the availability of
sys/un.h by compiling and running a small test program. Since we're
cross-compiling we can't run the generated program, however if the
header is missing the test will fail at the compilation step so
running the test in unnecessary.
