UDEVDIR is used in both `chreipl-fcp-mpath` and `zdev`, but with a different meaning. In the former it points to the base udev directory, not the rules directory; in the later it points to the rules directory. If someone was to call `make` from the top level directory, and set UDEVDIR for the whole build/installation, it would either break `zdev` or `chreipl-fcp-mpath` (depending on what it was set to). Fix this by pulling the definition of it in the shared `common.mak` file, and giving it a common meaning. Point UDEVDIR to the base udev directory, and UDEVRULESDIR to the rules directory below it. Semantically nothing changes for a default build/installation.
