When execve() fails with ENOEXEC, glibc's execvp() and execvpe() retry the file as a shell script via /bin/sh. Hence a truncated (e.g. empty) binary is run as an empty shell script and exits successfully, instead of failing with ENOEXEC. musl doesn't do this. Let's add variants that look up the file in $PATH via find_executable() and then call execve(), so that ENOEXEC is propagated to the caller.
