chg: use --daemon-postexec chdir:/ instead of --cwd /
The chgserver is designed to load repo config from current directory. "--cwd /"
will prevent chgserver from loading repo config and generate a wrong
confighash, which will result in a redirect loop. This patch removes "--cwd /"
and uses "--daemon-postexec chdir:/" instead.
