util/qemu-openpty.c: Don't assume pty.h is glibc-only

Browse source 
Instead of using an OS-specific ifdef test to select the "openpty()
is in pty.h" codepath, make configure check for the existence of
the header and use the new CONFIG_PTY instead.

This is necessary to build on Haiku, which also provides openpty()
via pty.h.
