LoongArch: BPF: Enable bpf_probe_read{, str}() on LoongArch
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 0ebeea8ca8a4d1d ("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.
