gdb/Cygwin: Fix attach pid error message
On Cygwin, with "attach PID":
- GDB first tries to interpret PID as a Windows native PID, and tries
to attach to that.
- if the attach fails, GDB then tries to interpret the PID as a
Cygwin PID, and attach to that.
If converting the user-provided PID from a Cygwin PID to a Windows PID
fails, you get this:
(gdb) attach 12345
Can't attach to process 0 (error 2: The system cannot find the file specified.)
Note "process 0".
With the fix in this commit, we'll now get:
(gdb) attach 12345
Can't attach to process 12345 (error 2: The system cannot find the file specified.)
I noticed this while looking at gdb.log after running
gdb.base/attach.exp on Cygwin.
