Subject: [PATCH] Bump bpf-tools to version v1.5 (#16331)

The new version of bpf-tools eliminates the separate
rust-bpf-sysroot. The Rust standard libraries for the BPF target are
built in tree when the compiler is built.  The standard libraries code
is slightly more optimized and some reduction of compute budget can be
expected with this version of bpf-tools.
