.bashrc.d/20nobeep: Change '-blength' -> '--blength'

setterm from util-linux 2.25.2 uses GNU-style, double-dash long
options.  I'm not exactly sure when the change took place, but
util-linux 2.24.1 used single-dash long options.  2.25.2 also supports
the single-dash versions, but I don't need to be backward compatible
;).
