busterjs/posix-argv-parser: example does not run

[andy-hanson]

First, posixArgvParser on line 38 needs to have its name changed to pap.
After that, it still doesn't run.

$ node mything.js --port=1234 path/to/stuff
Unknown argument '--port=1234'.

@andy-hanson, it has to be "args" not "pap". I have fixed the example. Thanks for the hint.
