xcheck
cargo xtask shows "stable" instead of the expected "nightly" from the rust-toolchain.toml file
in the xcheck-bpf subdirectory.
A change like in aya-rs/aya-template#79 (use rustup run nightly cargo -V)
works around the issue.
Run 'cargo -V' in the xcheck-ebpf subdirectory:
Current dir: "\\\\?\\C:\\Users\\dmitris\\dev\\tmp\\xcheck\\xcheck-ebpf"
status: exit code: 0
