lib/oe/recipeutils: fix a few issues in find_layerdir()
* Allow the function to be called with the base layer path (in which case it will just return the same path) * Ensure that the function doesn't recurse indefinitely if it's called on a file that's not inside a layer * Correct the doc comment for accuracy (From OE-Core rev: 912026d85c2f535be2f60c45979162ea25c7f356) Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
