[PATCHv2 perf/core 13/22] selftests/bpf: Rename uprobe_syscall_executed prog to test_uretprobe_multi

[Jiri Olsa <jolsa@kernel.org>]

Renaming uprobe_syscall_executed prog to test_uretprobe_multi
to fit properly in the following changes that add more programs.

Plus adding pid filter and increasing executed variable.
