Subject: [PATCH bpf-next] samples/bpf: Add missing -lz to TPROGS_LDLIBS

Since libbpf now links against zlib, this needs to be included in the
linker invocation for the userspace programs in samples/bpf that link
statically against libbpf.

Fixes: 166750bc1dd2 ("libbpf: Support libbpf-provided extern variables")
