selftests/bpf: Add test for raw-address single kprobe attach

Currently, attach_probe covers manual single-kprobe attaches by
func_name, but not the raw-address form that the PMU-based
single-kprobe path can accept.

This commit adds PERF and LINK raw-address coverage. It resolves
SYS_NANOSLEEP_KPROBE_NAME through kallsyms, passes the absolute address
in bpf_kprobe_opts.offset with func_name = NULL, and verifies that
kprobe and kretprobe are still triggered. It also verifies that LEGACY
rejects the same form.
