[OE-core] [PATCH] utility-task: Add do_patchall task

[Matthew McClintock]

This is useful in a few scenarios:

1) A developer wants to be able to grep all the code in a particular
without having to run patch on various components until they guess the
right one (e.g. which component is generating an error/warning?)

2) Other code scanning tools that can be run without requiring a full
image to be built (legal, static code analysis, etc)
