[tarantool-patches] [PATCH v4 3/4] box-tap: syslog destination test unix socket

[Olga Arkhangelskaia <arkholga@tarantool.org>]

Adds syslog destination unix test in box-tap.
Test redirects logs to newly created unix socket and sets appropriate
log level. If log receives the same level - test passes. In case if
syslog is not configured we use pcall.

Closes #3487
