t: Reduce timeout of t/44-scripts.t again after stabilization

[okurz]

We just increased the timeout recently in 4e00e6b but it seems we
needed to workaround a temporary problem as I can confirm with
reproducible runs that the normal expected runtime is well below the
specified timeout value so we can reduce it again a bit.
