[OE-core] [PATCH 09/10] lib/oe/recipeutils: fix invalid character detection in validate_pn()

[Paul Eggleton]

* validate_pn() is supposed to protect against invalid characters, fix
  the function so that it actually does (unanchored regex strikes
  again...)
* However, now that the function is enforcing the restrictions, we do
  still want to allow + in recipe names (e.g. "gtk+")
