remove -Werror from AM_INIT_AUTOMAKE

While this is nice while developing, it may cause
various problems with distributed tarballs.

A new automake version could add a warning, causing errors for distributions
and users, who might need to patch configure.ac and thus run autoreconf.

For example, we hit an error where a third party package (gettext) uses
functionality (AM_PROG_MKDIR_P) which is deprecated in newer automake versions(1.12.1),
causing the powertop build to fail.

Since the problem lies elsewhere, it is stupid to fail for this while building powertop
