[Bug 9628] msiexec command line parsing incorrect

I think I've worked out what's going wrong.

Basically the way RPG Maker XP is calling CreateProcess is by passing in the
msiexec executable as the appname and cmdline as " /i .....". This is slightly
different from most other cases where an application is started by passing the
entire commandline to CreateProcess, or in certain cases duplicating the
exename in the cmdline string.

I've eliminated the problem in build_argv that I previously though was present.

Using the function CommandLineToArgvW instead of process_args results in the
appname being added to the commandline and therefore becomes argv[0], however
it doesn't guarantee that remaining args are reconstructed as required.

So either changes need to be made to CommandLineToArgvW to change what it
returns so that its suitable for msiexec, or modify process_args to also
include the appname.
