bpf: Introduce bpf_sysctl_get_name helper
Add bpf_sysctl_get_name() helper to copy sysctl name (/proc/sys/ entry)
into provided by BPF_PROG_TYPE_CGROUP_SYSCTL program buffer.
By default full name (w/o /proc/sys/) is copied, e.g. "net/ipv4/tcp_mem".
If BPF_F_SYSCTL_BASE_NAME flag is set, only base name will be copied,
e.g. "tcp_mem".
Documentation for the new helper is provided in bpf.h UAPI.
