tests: Fix socket addr lengths in unix_socket/unix_socket_client

Browse Source 
Instead of using the entire sun_path buffer for abstract socket names,
only use the exact length of the string that is specified on the command
line. The nul-terminator is not included for abstract sockets.

The size of sun_path is modified to include the nul-terminator for
pathname address types.
