Subject: [PATCH] main.c: if OEPYTHON3HOME is set use instead of PYTHONHOME

There is one variable PYTHONHOME to determine where libraries are coming
from for both python2 and python3. This becomes an issue if only one has
libraries in the specified PYTHONHOME path, but they are using the same
PYTHONHOME. Creating another variable OEPYTHON3HOME to allow for a way
to set a different path for python3

Upstream-Status: Inappropriate [OE specific configuration]
