wip: D-Bus root user uid fix (patch created, needs tar strip fix)

Changed <policy user="root"> to <policy user="0"> in D-Bus
system.conf.in to avoid getpwnam lookup failures on Redox.

Patch written but does not apply yet — tar source extraction
puts files under dbus-1.16.2/ which requires strip=2 or different
path prefix. Left as documented work-in-progress.

D-Bus daemon runs despite cosmetic user lookup warnings.
