package_rpm: Fix useradd preinst ordering issues1.2_M4.rc3

We were already having occasional ordering issues with package_rpm.
Fixing the ldconfig postinstall issue pushed rpm over the cliff and
totally broke rpm builds with the packages getting installed in
effectively a random order and the useradd preinstalls getting executed
out of order and breaking.

The only explanation I can find for this is that rpm is special. It will
happily run a preinst for a package without any of that package's
dependencies being present regardless of whether there are any circular
dependency issues or not. I attempted various ways of solving this such
as ordering the total_solution.manifest in creative ways but the bottom
line is RPM ignores this. It takes little account of any request to
ignore /bin/sh dependencies for the purposes of constructing the final
image.

The end result is we're having to install the base-passwd, base-files
and shadow packages first (if there is a request to install them), then
install any other packages.

It this wasn't in the middle of a release I'd be rewriting this bbclass
file, its horrible.
