python-imaging: bring in fixes from meta-oe

This makes the following changes:
* Replace the /usr/local/bin/python path in all scripts
* Move RDEPENDS_${PN} to the end (but use += or we lose the python-core
  depencency).
* Use PR = "r3" instead of "ml2". (Even without increasing the numeric
  part it is recognised as greater alphabetically.)
* Bring in meta-oe version of the path patch which avoids the following
  warning:

WARNING: python-imaging: The compile log indicates that host include
and/or library paths were used.
