[Bug 10618] dll/kernel32/process. c build_argv returns incorrect argv array for a given command line string

http://bugs.winehq.org/show_bug.cgi?id=10618

Following code snippet causes argv to be created correctly for this case, but
its hardly code that should be committed. Need to sit down and actually work
out how it should determine what is an escaped quote and when it is just a
quote preceded by a backslash.
