[OE-core] [PATCH] sstate: Fix an error handling the taskname

[Richard Purdie]

Looking at the code, its clear 'task' is meant not to have the do_ prefix,
however its also clear it can be left in through some code paths.

One result of this can be files not being cleaned from the sysroot correctly.

Fix this.
