package/pkg-autotools: set AUTOPOINT via AUTOCONF_ENV

Previously, AUTOPOINT was hardcoded to /bin/true in autoconf.mk.

Moving the definition of this variable into AUTOCONF_ENV as part of the
autotools infrastructure will allow us to conditionally set the variable
based on package flags to support migrating away from FOO_GETTEXTIZE.

While we're at it, split the overly long line that defines AUTORECONF,
wrapping at 80 columns.
