scripts/oe-buildenv-internal: improve the error detecting for $BDIR
The previous fix for a bug in Ubuntu 10.04 readlink,
be2a2764d8ceb398d81714661e6f199c8b11946c, notified the user when a trailing
slash was used. As there is no semantic difference, simply remove any
trailing slashes and proceed without nagging the user.
See [YOCTO #671] for more details.
