[PATCH v2] bitbake.conf: drop obsolete comment refering to the fail-fast over-ride

[Andre McCurdy <armccurdy@gmail.com>]

The comment appears to have been accidentally left behind when the
fail-fast over-ride was removed by:

  http://git.openembedded.org/openembedded-core/commit/?id=83ce96f44516c8a4a44c8c0140949256f8422014

Also update comments to refer to bitbake variables as just variables,
rather than environment variables.
