    oe-buildenv-internal: Fix finding build directory
    
    The intent of the env setup scripts is to set BBPATH to point at the
    build directory. This means if the user changes directory, bitbake can
    still find the original build directory. The default bblayers.conf files
    reset BBPATH to the correct components so this is safe and restores the
    behaviour the script was intended to have.
