Add check for CONFIG_CGROUP_BPF in check-config.sh

Browse Source 
cgroup v2 requires CONFIG_CGROUP_BPF kernel option to be set
else runc can not start containers.

check-config.sh script checks if the CONFIG_CGROUP_BPF option
is set. The script checks if version of kernel is atleast
4.15 and cgroup v2 is being used before checking if the
CONFIG_CGROUP_BPF option is set.

Closes #3547
