Subject: [PATCH] CMakeList.txt: Don't download libbpf source when system
 library is used

Upstream-Status: Backport [https://git.kernel.org/pub/scm/devel/pahole/pahole.git/commit/?id=3d20210d84f61ee2189927e2d9de9ce3e5a0a9c5]

The build system always download the libbpf submodule, regardless if
we're using the embedded or the system version.
Download the libbpf source only if we're using the embedded one.
