libbpf: Fix gen_loader assumption on number of programs.
libbpf's obj->nr_programs includes static and global functions. That number
could be higher than the actual number of bpf programs going be loaded by
gen_loader. Passing larger nr_programs to bpf_gen__init() doesn't hurt. Those
exra stack slots will stay as zero. bpf_gen__finish() needs to check that
actual number of progs that gen_loader saw is less than or equal to
obj->nr_programs.
Fixes: ba05fd36b851 ("libbpf: Perform map fd cleanup for gen_loader in case of error")
