perf bpf: Make bpf__for_each_stdout_map() generic
By passing a 'name' arg, that will eventually be used to setup more "bpf-output" events, e.g. to create a event where to create raw_syscalls like events that in addition to the syscall arguments will also copy the pointer contents being passed from/to userspace.
