Remove "--clean" option from autogen.sh

autogen.sh seems to be used as a preprocessor for configure script,
so it has only a few options itself. However, "--clean" option,
which is even documented in script's help message, now touches only
two items in repository (on Windows): autom4te.cache folder,
which is refreshed during autogen.sh run anyway, and install-sh
script, which is NOT regenerated afterwards. So using --clean
actually breaks configuration setup.
Please check if anyone still uses --clean for its original purpose
and remove this feature or automate install-sh regeneration.
