oe-buildenv-internal: Fix BITBAKEDIR changes to work with existing autobuilder scritpts

The BITBAKEDIR change does not work well when the script is sourced from another script
since $2 may be unrelated. This change adds the logic onto the BDIR conditional and
which more external scripts would set, hence avoiding the problem.
