util-linux: enable AUTORECONF

Commit 55a9737895cb ("util-linux: link scriptreplay with libm (for isnan)")
added two patches that touch configure.ac and Makemodule.am. But forgot
to enable AUTORECONF.

When AUTORECONF is disabled and configure.ac is patched, it looks like
make will detect change in timestamps and trigger reconfig. But it
later fails because of missing dependencies. To fix this, explicitly
enable AUTORECONF.

I'd prefer to avoid autoreconf but looks like it is required, so,

Acked-by: Carlos Santos <casantos@datacom.ind.br>

I was unable to reproduce 544e8da290d40424ea3d1bffad7e0b8a566de495 on my
machine (Fedora release 24). It can be related to the build environment.

In principle autoreconf is harmless but it adds around 10 seconds of build
time and 10 seconds more for host tools (host-{libtool,autoconf,automake}).

Mystery solved: automake is installed on my machine, so /usr/bin/aclocal-1.15
is used when host-automake is not built.
