[OE-core] [PATCH 07/17] package.bbclass: Add a shortcut exit from the mkdir function

[Richard Purdie]

The mkdir function iterates over strings with many different operations,
even if ultimately the target already exists. This adds a check to the start
of the function so we don't waste time when the target already exists.
