  Script: Allow signed integers as module func params

This fixes a regression where the behavior of some OpenSIPS 2.4 module
functions was restricted in 3.0, e.g. is_from_gw():

In 2.4:
    is_from_gw("-1", "n", "$var(gw_attr)") # starts OK

In 3.0 (without this patch):
    is_from_gw(-1, "n", $var(gw_attr)) # would fail to start
