[packages] reintroduce fakeidentd (#11559)
In the transition from WhiteRussian to Kamikaze, the fakeidentd package was dropped, citing its incorporation into the updated Busybox. However, the Busybox implementation doesn't support the -r switch, which is a bit silly,
since it's pretty much fakeidentd's raison d'etre. This patch restores the fakeidentd package, with an initscript that uses the -r option.
