fc-iram: added '+' to getopt magic string like in fc-xram
Both fc-iram and fc-xram now support secondary program invokation.
If the user needs to pass some options to the secondary program,
we don't want fc-iram or fc-xram to claim these options as its own,
thus we need to stop getopt() from reordering arguments. This fix
was already implemented in fc-xram a long time ago, but the issue
was overlooked when secondary program invokation ability was added
to fc-iram.
