sysctl_kernel_kptr_restrict should pass with stricter value

#### Description of problem:

Apply to the rule `sysctl_kernel_kptr_restrict`

This rule check that `kernel.kptr_restrict=1`, but there is also a `2` value that is stricter and more secure (REF: [Kernel documentation](https://www.kernel.org/doc/html/latest/admin-guide/sysctl/kernel.html#kptr-restrict)).

The test should pass with both `1` and `2` values.
