useradd has sstate [depends] for both do_package and do_populate_sysroot
yet the dependency validation code only covers do_package.
Add coverage of populate_sysroot, else the order inversion that [depends]
creates means unexpected installation of users of useradd.bbclass (e.g.
avahi do_populate_sysroot) in cases where it shouldn't be (e.g.
libnss-mdns -c packagedata).
The code needs to move above the other populate_sysroot intercept code
since there are specific cases we need to cover before that code.
The result of this change is more optimal installation of sstate objects
in common usage scenarios.
