Add timer_create syscall to system-probe seccomp profile

[gjulianm]

What does this PR do?

Adds the timer_create syscall to the allowed syscalls list in the system-probe seccomp profile.

Motivation

The Go runtime now uses the timer_create syscall for CPU profiling as of Go 1.23+ (see
golang/go@8cfd8c3). This PR adds it to the seccomp list so that profiling data is more accurate

Additional Notes

Minimum Agent Versions

No minimum version changes required.

Describe your test plan

Ensure that the timer_create syscall is present in the configmap data.
