When ubus is running as root, /var/run/ubus most likely hasn't been
created as well (as that's the homedir of user ubus, and if a user
ubus was found, then ubus would run being that user).
Blindly attempt to create the directory (which won't do any harm if
it does exist and/or ubus is not running as root) to still be able to
start ubus in case of user ubus not existing.

In commit 5d7ca8309d ("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.
