This prevents docker from setting CAP_PERFMON, CAP_BPF, and CAP_CHECKPOINT_RESTORE
capabilities on privileged (or CAP_ALL) containers on Kernel 5.8 and up.
While these kernels support these capabilities, the current release of
runc ships with an older version of /gocapability/capability, and does
not know about them, causing an error to be produced.
We can remove this restriction once 6dfbe9b807
is included in a runc release and once we stop supporting containerd 1.3.x
(which ships with runc v1.0.0-rc92).
Thanks to Anca Iordache for reporting.
