BUG/MINOR: startup: set GTUNE_SOCKET_TRANSFER correctly
This bug was forbidding the GTUNE_SOCKET_TRANSFER option to be set
when haproxy is neither in daemon mode nor in mworker mode. So it
basically only impacts the foreground mode.
The fix moves the code outside the 'if (global.mode & (MODE_DAEMON |
MODE_MWORKER | MODE_MWORKER_WAIT))' condition.
Bug was introduced with
7f80eb23 ("MEDIUM: proxy: zombify proxies only
when the expose-fd socket is bound").
Must be backported in every stable version.
