util-linux: add minimal uuidgen implementation
Add a simple uuidgen utility that generates RFC 4122 compliant
UUIDs (version 4, random). Uses the existing generate_uuid()
function from libbb and volume_id_set_uuid() for formatting.
Implementation suggested by Ulli.
Features:
- Generates standard format UUIDs: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
- RFC 4122 version 4 compliant
- Minimal implementation (~1.1 kb)
- NOFORK applet for efficiency
- Uses existing volume_id infrastructure for UUID formatting
