module-init-tools: bump version + convert to autotools

The "remove-index" patch is no longer needed, the newer version of
module-init-tools correctly uses strchr().

The "module-init-tools" patch, whose main purpose was to disable the
generation of man pages (it requires docbook2man), is replaced by a
simpler implementation,
module-init-tools-3.11-add-manpages-config-option.patch.
