udev: run programs in the specified order

This fixes bugs introduced by 29448498c7
and d838e14515.

Previously, RUN and SECLABEL keys are stored in udev_list with its unique
flag is false. If the flag is false, then udev_list is just a linked
list and new entries are always added in the last.
So, we should use OrderedHashmap instead of Hashmap.

Fixes #11368.
