[OE-core] [PATCH] package: Drop do_package_write task

[Richard Purdie]

The reasons this task was introduced are lost in the mists of time. It
allowed for the a single "package_write" task instead of spelling out
the explicit package backends, however in all but one case we do that
anyway.

As such as might as well give in and delete the task, converting that
single reference into explicit dependencies.

This gives bitbake a bit less work to to when processing the runqueue
since there are less tasks (but more dependencies in some cases).
