HID: bpf: allow to use bpf_timer_set_sleepable_cb() in tracing callbacks.
Export the sleepable kfuncs we have on HID-BPF in tracing bpf programs,
but with the condition of being used in a sleepable context.
This allows to use the bpf_timer when used in a sleepable context
through bpf_timer_set_sleepable_cb() and initiate work from a device event.
