libmakepkg/executable: don't rely on scoped value of $ret to flag outcomes

Elsewhere, we return 1 if a library dropin fails, and when running
functions in a loop, we use `|| ret=1` to preserve scope. This ensures
the return value of the function remains useful in isolation. Do the
same thing here as well.

Drop trivial function which wraps a dropin that also uses $ret, since
it's no longer needed.
