[PATCH v2] tests/syslog: GSOC Microproject: Modify test to pass imposed LSM configs

[Bharath Vedartham]

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

Add test case to cover rest of the default cases.

PS: I am looking to apply for Gsoc. This is my first patch to strace.

Changes in v2:
    - Used SYSLOG_ACTION_CLEAR which is a privileged instruction. This will fail before the LSM hooks.
