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.
