LoongArch: BPF: Enable bpf_probe_read{, str}() on LoongArch

Browse source

Currently nettrace does not work on LoongArch due to missing
bpf_probe_read{,str}() support, with the error message:

     ERROR: failed to load kprobe-based eBPF
     ERROR: failed to load kprobe-based bpf

According to commit 0ebeea8ca8 ("bpf: Restrict bpf_probe_read{,
str}() only to archs where they work"), we only need to select
CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE to add said support,
because LoongArch does have non-overlapping address ranges for kernel
and userspace.
