bitbake: bitbake: Handle BBMainException

Some error messages were lost because BBMainException was
inherited from bb.BBHandledException. When bb.BBHandledException
is processed error messages are not printed as they suppose to
be printed before raising this exception.

Stopped to inherit BBMainException from bb.BBHandledException.
Handled BBMainException in bin/bitbake and printed error message
to the stderr.
