lsb: fix lsb_log_msg() implementation

LSB lsb_log_message calls a begin()
function that should be implemented
in /etc/init.d/functions.
The aforementioned script does not
implement the begin() function, as
such there is a small issue related to logging.

This fix implements a local version of
the function, while cleaning up the
troublesome previous implementation.
