Subject: oe-buildenv-internal: Only add to $PATH if needed

If $PATH already has the needed paths at the beginning, there is no need
to add them again. This allows rerunning oe-init-build-env for the same
directory without having $PATH increase unnecessarily every time.

(From OE-Core rev: 161abcd3672f83990ede03d67b7388678c07150e)
