execv_dashed_external: stop exiting with negative code
When we try to exec a git sub-command, we pass along the
status code from run_command(). But that may return -1 if we
ran into an error with pipe() or execve(). This tends to
work (and end up as 255 due to twos-complement wraparound
and truncation), but in general it's probably a good idea to
avoid negative exit codes for portability.
We can easily translate to the normal generic "128" code we
get when syscalls cause us to die.
