Switch rocky9's GitHub-hosted dependency downloads from `git clone` to
curl-fetched release tarballs via the wangguofang.net proxy, matching

git clone since it needs a submodule checkout.

Build libunwind 1.8.3 as a static library before jemalloc, then
configure jemalloc with --enable-prof --enable-prof-libunwind so the
static libjemalloc.a can dump heap profiles with accurate stack
traces.
