headerscheck: Ignore Windows-specific header

Ignore src/include/port/win32/sys/resource.h.  At least on macOS,
including this results in warnings and errors because of duplication
with system headers:

../src/include/port/win32/sys/resource.h:10:9: warning: 'RUSAGE_CHILDREN' redefined
../src/include/port/win32/sys/resource.h:16:1: error: redefinition of struct or union 'struct rusage'

Since we are also not checking similar system-replacement headers for
Windows, it makes sense to exclude this one, too.
