r11502: make sure we always use the 7 chars for the unix socket name.

this is to test if that works on irix 6.4 where we can only use 16 chars for the sun_path
of the unix sockets.

the plan is to make multiple interfaces possible with socket wrapper,
and the format will change to ("%c%02X%04X", type, iface, port),
which is also 7 char to the file name
