[Toybox] Allow --help after other arguments?

[Ryan Prichard]

It seems to have broken --help when invoking toybox explicitly:

$ ./toybox ls --help
<shows same output as "./toybox --help" rather than the "toybox ls" usage.>

Are we concerned about interpreting "data" arguments as the --help flag?
e.g.:

$ ./rm -- --help
<prints usage rather than remove the file named "--help">

$ ./tar -c README > --help && tar -tvf --help
-rw-r----- rprichard/primarygroup 6306 2021-06-08 19:10 README

$ ./tar -c README > --help && ./tar -tvf --help
<prints "toybox tar" usage with the new --help behavior. previously toybox
behaved like GNU tar above.>
