debuginstall: strip double quotes from editorbin on Windows

The unconditional posix style shlex.split() prior to 94a1ff16f362 handled this.
This isn't mutually exclusive with stripping the quotes in util.findexe()- if
the editor can't be found, this command prints out the string, inside single
quotes.
