[Tarantool-patches] [PATCH v1] Output for sockets issues cuts its names in logs

["Alexander V. Tikhonov" <avtikhon@tarantool.org>]

Found issue in log files:

  2020-08-10 11:47:07.191 [73298] iproto sio.c:268 !> SystemError writev(1), called on fd 31, aka unix/:/Users/tntmac01.tarantool.i/tnt/test/var/001_r: Broken pipe

when it cut the socket name. The length of the socket name based on:

  src/lib/core/sio.h:enum { SERVICE_NAME_MAXLEN = 32 };
  src/lib/core/sio.c:	int name_size = 2 * SERVICE_NAME_MAXLEN;

Decided to increase multiplication of the name_size from 2 to 4.

Closes #5246
