tweeper: avoid a reference to $argv in non-cli mode

$argv is not defined in non-cli mode, so protect its usage behind an
is_cli() check.

For instance, this avoids a message in the PHP built-in web server, when
usage() gets called:

  PHP Notice:  Undefined variable: argv in .../tweeper.php on line 357
