board configs: disable unprivelaged BPF

Fixes wrong CPU vulnerability output:

/sys/devices/system/cpu/vulnerabilities/spectre_v2:Mitigation:Vulnerable:
Unprivileged eBPF enabled

It's enabled but CONFIG_BPF_UNPRIV_DEFAULT_OFF being unset causes the
warning.

This warning happens on ARM32 and ARM64 devices.

Edited with:
find -name "*.config" -exec sed -i 's/# CONFIG_BPF_UNPRIV_DEFAULT_OFF is not set/CONFIG_BPF_UNPRIV_DEFAULT_OFF=y/g' '{}' \;
