cooker: fix file changes not triggering task re-execution with memres
If you build a recipe, modify one of the files referred to in SRC_URI,
then build it again, it should re-run do_fetch and the tasks that depend
upon it to incorporate the modified file. With memory resident mode this
was not working unless you restarted the server, because the mtime of
the file was cached and thus we never checked the actual file. Clear out
the mtime caches in buildTargets() to ensure this isn't an issue. I did
a minor refactoring to break this out to its own function since we were
already clearing out the build mtime cache here.
(The test I used for this was . ./oe-init-build-env-memres,
bitbake -c fetch mdadm, modify the comments at the top of one of the
patches referred to in the recipe, and then bitbake -c fetch mdadm again
and it should re-execute the fetch task ("... 0 didn't need to be
re-run".)
Fixes [YOCTO #10732].
