basevm: Call logging.basicConfig()

Just setting level=DEBUG when debug is enabled is not enough: we
need to set up a log handler if we want debug messages generated
using logging.getLogger(...).debug() to be printed.

This was not a problem before because logging.debug() calls
logging.basicConfig() implicitly, but it's safer to not rely on
that.
