BPF jiffies never enabled due to missing /proc/timer_list #25463

Description

@pchaigno

#11434 introduced a new flag enable-bpf-clock-probe to use jiffies instead of bpf_ktime_get_sec which can be expensive. This feature however always fails to enable due to the missing /proc/timer_list file. I think that's because we don't mount that file in the agent container.
