main/client: be POSIXLY_CORRECT when parsing command line

Browse source 
This means command line parsing stops when it encounters the first
nonoption argument.

The result is that one no longer need to use '--' to ensure arguments
are passed to the shell/command, instead of parsed by foot.

That is, instead of

  foot -- sh -c true

one can now do

  foot sh -c true

Arguments to foot *must* go before the command:

  foot --fullscreen sh -c true
