integration-test: distinguish between success and noop
These tests previously produced the same result on certain failures as
they did on success.

Clippy over tests and integration-ebpf
Replace all `assert!(matches!(..))` with `assert_matches!(..)`.

Remove the now-unused build-integration-test xtask command whose logic
doesn't match that of the build-and-run command.

Alessandro Decina 11c227743d bpf: improve bpf_probe_read_kernel_str_bytes and bpf_probe_read_user_str_bytes
This change does a few things:

- it fixes a bug in the wrappers, where we were expecting the kernel to
  return len=1 for b"\0" where it instead returns 0 and doesn't write
  out the NULL terminator

- it makes the helpers more robust by hardcoding bound checks in
  assembly so that LLVM optimizations can't transform the checks in a
  way that the verifier can't understand.

- it adds integration tests
