[OE-core] [PATCH] useradd.bbclass: Add explict setscene dependencies to ensure correct ordering of setscene tasks

[Richard Purdie]

This is the final piece of fixing the races in the useradd class by
ensuring base-passwd, shadow-native and shadow-sysroot are installed
before sstate packages which use useradd.

[YOCTO #1721]

NB: This patch depends on a change in bitbake to work but is harmless
without that change, just won't fix the race.
