autogen.sh: fix autoreconf step
autogen.sh: fix autoreconf step

Running bootstrap and autoreconf from autogen.sh produced different
files in build-aux directory.  The reason is that gnulib usually have
newer version of these files and overwrites them after the autoreconf
step.

In order to fix it remove the --install and --force options, in addition
introduce --verbose option in order to reflect what bootstrap is doing.
