sstate: Explicitly define populate_sysroot task relationships

Clean up and clarify the populate_sysroot task dependencies. Target sysroot
packages do need their dependencies installed, as do some target/cross
relationships. We can whitelist the *-initial dependencies as these are
never needed indirectly.
