configure: use PACKAGE_VERSION variable instead of VERSION

The AC_INIT macro will define the PACKAGE_VERSION variable:

http://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/Initializing-configure.html#AC%5fINIT

I kept the #define name `SYSLOG_NG_VERSION` for backward compatibility
with incubator.
