Daniel Borkmann 4f3ff11204 bpf: Use correct permission flag for mixed signed bounds arithmetic 
[ Upstream commit 9601148392 ]

We forbid adding unknown scalars with mixed signed bounds due to the
spectre v1 masking mitigation. Hence this also needs bypass_spec_v1
flag instead of allow_ptr_leaks.

Fixes: 2c78ee898d ("bpf: Implement CAP_BPF")
