ubusd/libubus-io: fix socket descriptor passing

In commit 5d7ca8309d0a ("ubusd/libubus-io: fix variable sized struct
position warning") the position of cmsghdr struct has been changed in
order to fix clang-9 compiler warning, but it has introduced regression
in at least `logread` which hanged indefinitely.

So this patch reworks the socket descriptor passing in a way recommended
in the `cmsg(3)` manual page.
