pipewire: utils: make_random(): do not use errno

Browse source 
The function already returns `ssize_t`, so do not use `errno`
to communicate the reason for failure, instead, return the
negative errno.

`pw_getrandom()` was inconsistent in this regard because
sometimes it simply returned a negative errno without
setting `errno`. This change fixes that as well.
