Cygwin: spawn: drop special handling for cmd.exe and command.com 

Apparently at one point handling cmd.exe and command.com special
made sense, but what that should be has never been documented.
There's also no clear reason why cmd.exe is different from any
other native executable.  Additionaly, checking for command.com
is entirely useless on 64 bit Windows anyway.

Just drop this code.
