perf test stat_bpf_counters_cgrp: Enhance perf stat cgroup BPF counter test
It has system-wide test and cpu-list test but the cpu-list test fails
sometimes. It runs sleep command on CPU1 and measure both user.slice
and system.slice cgroups by default (on systemd-based systems).
But if the system was idle enough, sometime the system.slice gets no
count and it makes the test failing. Maybe that's because it only looks
at the CPU1, let's add CPU0 to increase the chance it finds some tasks.

perf test stat_bpf_counters_cgrp: Fix shellcheck issue about logical operators
Running shellcheck on lock_contention.sh generates below warning:

Fixed above warnings by:
- Changing the expression [p -a q] to [p] && [q].
- Fixing shellcheck warnings for local usage, by prefixing
function name to the variable.
