systemctl: fix type used for array sizes to size_t

We always should use size_t for sizes of arrays (and any size of memory,
in fact), unless there's a strong reason to use something else. Hence,
let's fix these cases where we sloppily used "unsigned" or "int"
instead.

No change in behaviour, this is just to make things less surprising for
the random reader.
