user.eclass: Allocate next free UID or GID from 999 downwards.
Fixed UIDs and GIDs are mostly located in the low range, therefore
going downwards from 999 to 101 will minimise collisions between fixed
and dynamically allocated IDs.
Note that on Linux and other targets using "groupadd -r" from
sys-apps/shadow, GIDs are already allocated that way implicitly.
