This patch allows us to run the ci-buildworld and ci-buildkernel targets
as NON_ROOT.
In the future, when we are able to build a release image as NON_ROOT,
this can be further improved by moving the ci-buildimage target into
the top level 'ci' target.
This also implements the following minor fixes:
* Add a .WAIT directive before ci-extractmeta to avoid racing with
the ci-runtest target. This fixes the issue where ci-extractmeta
runs immediately upon running 'make ci'
* Create the META_* temp files/directories as the unprivileged user
and rename them to something human-readable.
* Cleanup as many temporary files as possible after they are no longer
needed.
