serve: rename --daemon-pipefds to --daemon-postexec (BC)

Initially we use --daemon-pipefds to pass file descriptors for synchronization.
Later, in order to support Windows, --daemon-pipefds is changed to accept a
file path to unlink instead. The name is outdated since then.

chg client is designed to use flock, which will be held before starting a
server and until the client actually connects to the server it started. The
unlink synchronization approach is not so helpful in this case.

To address the issues, this patch renames pipefds to postexec and the following
patch will allow the value of --daemon-postexec to be things like
'unlink:/path/to/file' or 'none'.
