package/bdwgc: drop AUTORECONF = YES

Since commit 4e1dbd063d1f3ea7dfc95698320f6fd40139085d ("package/bdwgc:
bump to version 8.0.0"), we no longer have any patch that requires
autoreconf. In addition, the libtool shipped with the package seems to
no longer be bogus, because it builds perfectly fine without
autoreconf. Therefore, let's drop this autoreconf.
