James Morse df53d41870 arm64: bpf: Only mitigate cBPF programs loaded by unprivileged users ...

[ Upstream commit f300769ead ]

Support for eBPF programs loaded by unprivileged users is typically
disabled. This means only cBPF programs need to be mitigated for BHB.

In addition, only mitigate cBPF programs that were loaded by an
unprivileged user. Privileged users can also load the same program
via eBPF, making the mitigation pointless.
