bugfix: lib/sh/util.sh: verbosity_compat(): always use default verbosity (`unset verbosity`) when verbosity == 1, regardless of whether the caller has set $verbosity to the special value "", because $verbosity is supposed to be an integer field and "" is not supported by most functions that use $verbosity. in cases where a util.sh script is invoked, it will set $verbosity back to the default value 1, so this will function as before for util.sh scripts and fix $verbosity for scripts that use a different verbosity system.
