osdep: hack to fix build with low quality pthreads-w32 headers 

When compiling semaphore_osx.c on win32, the following error happened:

/usr/i686-w64-mingw32/include/semaphore.h:160:6: error: unknown type name 'mode_t'

This is because this system header references symbols that are not
not defined anywhere. This is clearly a bug in pthreads-w32, but has
been known and unfixed since 2012, so add a hack to fix it.

We build semaphore_osx.c this way because it saves us an extra configure
check. On win32, Linux, etc. it's empty and contains
"#include <semaphore.h>" only.

Should fix #1108.
