selftests/bpf: Enable kprobe_multi tests for ARM64

The kprobe_multi feature was disabled on ARM64 due to the lack of fprobe
support.

The fprobe rewrite on function_graph has been recently merged and thus
brought support for fprobes on arm64.  This then enables kprobe_multi
support on arm64, and so the corresponding tests can now be run on this
architecture.

Remove the tests depending on kprobe_multi from DENYLIST.aarch64 to
allow those to run in CI. CONFIG_FPROBE is already correctly set in
tools/testing/selftests/bpf/config
