 [patch] fix: protect syscall probes with preemption disable

Since kernel v6.13, the syscall tracepoints call the probes from
faultable context (with preemption enabled).

Adapt to this change to ensure that the LTTng-modules per-cpu data
structures that expect preemption to be disabled don't get corrupted.

This has been noticed through a linked list corruption of the
lttng-tp-mempool per-cpu allocator.

This only affects preemptible kernel configurations (PREEMPT,
PREEMPT_LAZY).

Non-preemptible kernel configurations are not affected (PREEMPT_NONE,
PREEMPT_VOLOUNTARY).
