[PATCH 41/66] tests/xe_exec_sip: Add support for dynamic debugger sysfs toggle

[Christoph Manszewski]

>From now on the debugger is disabled by default so it is required
to enable the debugger before using it. This change addresses that
fact by calling necessary library functions within test fixtures.
