[OE-core] [PATCH] lib/oe: drop custom implementation of oe.path.relative

[Ross Burton]

As we now require Python 2.7 and os.path.relpath() was added in 2.6 we can now
drop the reimplementation in oe.path.

oe.path.relative is simple now a wrapper that changes the order of the arguments
and it's use discouraged.
