bug#10398: [PATCH] Use real vfork under Cygwin: it's fine these days

[Daniel Colascione <dancol@dancol.org>]

In Cygwin 1.7, vfork is an alias for fork.  The vfork the #define in
cygwin.h was protecting against is gone.  It's better to use vfork now
so that when Cygwin gains a new, working vfork, we use it
automatically.
