Strip symbols to setup.dbg

As noted in https://cygwin.com/ml/cygwin/2016-11/msg00254.html debugging the
distributed setup executable is a lost cause at the moment.  Preserve
symbols so it's not quite as hopeless.

Note: to debug the distributed setup executable with gdb, it will be
necessary to decompress the setup executable with 'upx -d', and, if the .dbg
file has been renamed to match the renamed setup executable, explicitly load
it into gdb with the 'symbol-file' command.
