packaging: Hardcode udev rules directory location to avoid cyclic dependency

DLog did build-depend on udev devel package, as it does provide information
where udev rules are located on the system in the form of RPM macros (_udevrulesdir).
udev is part of systemd, which caused libsystemd-devel package to be installed
for the build.

In situations where someone wants to use dlog in a library that is
required by systemd this would create a cyclic build dependency:
systemd -> dlog -> library -> systemd.
