The assertion is meaningless after this change. At least the log->type
check. I guess the idea was to check that json format isn't used in
conjunction with syslog.
Also, there's another similar assertion failure that I think should be
fixed in the scope of this patch:
box.cfg{log = 'syslog:identity=tarantool'}
require('log').log_format('json')
tarantool: /home/vlad/src/tarantool/src/lib/core/say.c:195: say_set_log_format: Assertion `log_default->type != SAY_LOGGER_SYSLOG' failed.

Squeezing a test case like this, without a proper comment, looks bad -
it seems that the comment above is related to it although it isn't.
Also, jlog is a bad name. If you don't want to pollute the namespace,
you can get along without it:
require('log').log_format('json')
