logrotate: bump version to 3.8.9

logrotate: bump version to 3.8.9

This version comes with a new build system based on autoconf/automake,
so we switch from generic-package to autotools-package. However, since
the tarball does not contain a pre-generated configure script, we have
to set LOGROTATE_AUTORECONF = YES.

[Thomas:
  - add comment explaining why AUTORECONF = YES is needed
  - expand commit log
  - use --without/--with instead of --with=yes/--with=no
  - fix indentation in the ACL condition]
