gh: generate lib/configure before running it in cflite build.sh

lib/configure is produced by autoreconf from lib/configure.ac and is
gitignored, not checked into the repository; the top-level ./configure
creates it on first use. .clusterfuzzlite/build.sh assumed it already
existed and failed immediately in CI ("./configure: No such file or
directory") since it only worked locally where it had already been
generated by a prior build. Run 'autoreconf -i' first, same as the
top-level ./configure does, before invoking lib/configure.
