[PATCH] sstate: Fix shared work preconfigure task handling

[Richard Purdie <richard.purdie@linuxfoundation.org>]

When the preconfigure task was added to gcc, it wasn't added to sstate's list
of possible shared work tasks. This meant that diffsigs wasn't able to find
the preconfigure sigdata/info file since it has inconsistent naming.

This adds the task name to the list. Ideally this list would be autogenerated
or not even required, right now its a sanity test that the shared work
code works as intended so is best left as is.
