[PATCH] Fix building tests under Windows

[Pavel Fedin]

1. grantpt.c seems to be never used on Windows, however it's still present in
tests/ subdirectory of the final project. Therefore it breaks 'make check'.

2. Windows has no PTYs, therefore gnulib's openpty() will just return -ENOSYS.
The main problem is test-openpty.c which expects termios to be there. Just make
it building and silently passing the test.
