[arch-projects] [initscripts][PATCH 2/2] arch-tmpfiles: don't try to resolve numeric UIDs/GIDs

[Dave Reisner]

The whole point of using numeric IDs is to avoid resolution in the
passwd/group databases. If we encounter an ID which is simply numeric,
leave it alone.

Looks like I broke this in a4558c4c trying to be a bit too clever.
