gnulib-tool: Fix description of --lgpl option (missed on 2021-06-04)

[Bruno Haible]

On 2021-06-04, gnulib-tool stopped doing license template replacements in the
source files. gnulib-tool's --help message was not updated at that time. This
patch does it now.

        gnulib-tool: Fix description of --lgpl option (missed on 2021-06-04).
        * gnulib-tool.sh (func_usage): Remove "Also modify license template"
        sentence.
        * pygnulib/GLInfo.py (GLInfo.usage): Likewise.
