cmd.exe: Locate programs more correctly.

Here is the console sequence that works before this commit.
Note from a clean prefix add a small autoexec.bat file to c:\

paul@paul-semipron:~/Git/wine-git$ WINEPREFIX=~/.wineautotest ./wine cmd
CMD Version 0.9.31

Z:\home\paul\Git\wine-git>c:
c:>cd windows
c:\windows>c:\autoexec.bat
File not found

There is a second regression in the later code that when the above sequence is
tried instead of file not found it gets into a loop and requires a ^C to
recover the console.
