Subject: [PATCH] libbpf: Remove the duplicate checking of function storage

After the commit eac7d84519a3 ("tools: libbpf: don't return '.text'
as a program for multi-function programs"), bpf_program__next()
in bpf_object__for_each_program skips the function storage such as .text,
so eliminate the duplicate checking.
