Cygwin: strace: print windows and cygwin pid in event output

Browse Source 
strace only printed the Windows PID in event output so far.

Especially now that Windows and Cygwin PID are decoupled, the
strace user might like to see the Cygwin pid in event output as
well.  However, at process startup, the process might not have
a Cygwin PID yet.

To mitigate this, always print the Windows PID and only add the
Cygwin pid if it exists.
