libbpf: Fix printing of ulimit value
Naresh pointed out that libbpf builds fail on 32-bit architectures because
rlimit.rlim_cur is defined as 'unsigned long long' on those architectures.
Fix this by using %zu in printf and casting to size_t.
Fixes: dc3a2d254782 ("libbpf: Print hint about ulimit when getting permission denied error")
