package/libxml2: Remove autoreconf
Autoreconf is not necessary since we do not patch this package anymore.
LIBXML2_AUTORECONF was added back in 2012
https://git.busybox.net/buildroot/commit/package/libxml2?id=aa5d9ba3b86f21be934fdb436525a833bf120305
and apparently not removed along with the patches applied before
