[PATCH v0 2/3] posix03, posix04: Use '-l' instead of '-i' as option argument name

[Daniel Wagner <wagi@monom.org>]

From: Daniel Wagner <daniel.wagner@bmw-carit.de>

All other test use '=l' instead of '-i' to as option name for defining how many
loops should be executed. Let's streamline posix03 and posix04.
