cooker/taskdata: Make NoProvider errors non-fatal to -e/-g options

If you have a situation where you are getting a "Nothing PROVIDES" error
(for example when something you request to build DEPENDS on something
that has been skipped or doesn't exist) it would be useful to be able to
use bitbake -g or bitbake -e to debug it, but currently both of those
are blocked by the error.

This patch adds an "allowincomplete" option to taskdata and uses this
for the -e/-g bitbake options. The NoProvider errors are still
printed and bitbake does return an error exist code but the environment
and task graph files are generated.
