tests: extend coverage of syslog tests

The current syslog test covers only those cases where the type parameter
is one of SYSLOG_ACTION_READ, SYSLOG_ACTION_READ_ALL,
SYSLOG_ACTION_READ_CLEAR as per codecov.

Add test case to cover the default case.

* tests/syslog.c (SYSLOG_ACTION_SIZE_BUFFER): New macro.
(main): Check SYSLOG_ACTION_SIZE_BUFFER decoding.
