[tarantool-patches] [PATCH v4 4/4] box-tap:syslog remote destination test

[Olga Arkhangelskaia <arkholga@tarantool.org>]

Adds syslog remote destination test in box-tap.
Test creates server, sets appropriate log level and redirects logs
to it. If log level received by the server is the same - test passes.
If syslogd is not running we use pcall.

Closes #3487
