RHEL-08-010671 and RHEL-08-040282 missing paths per STIG

#### Description of problem:
The DISA STIG for RHEL-08-010671 (RHEL 8 must disable the kernel.core_pattern) is here: https://www.stigviewer.com/stig/red_hat_enterprise_linux_8/2023-09-11/finding/V-230311

The DISA STIG for RHEL-08-040282 (RHEL 8 must restrict usage of ptrace to descendant processes) is here: https://www.stigviewer.com/stig/red_hat_enterprise_linux_8/2023-09-11/finding/V-230546

These are two separate STIGs, but they are related because they suffer the same issue.

The SCAP Security Guide only searches the paths for:
- `/etc/sysctl.d/`
- `/run/sysctl.d/`
- `/usr/local/lib/sysctl.d/`

In RHEL-08-010671, the check text ***requires*** that all instances of `kernel.core_pattern` must be exactly `kernel.core_pattern=|/bin/false` _even if the files are not loaded by `sysctl --system`_

However, per the STIG, it requires all conf files to be updated in the following directories:
> Check that the configuration files are present to enable this kernel parameter.
> `$ sudo grep -r kernel.core_pattern /run/sysctl.d/*.conf /usr/local/lib/sysctl.d/*.conf /usr/lib/sysctl.d/*.conf /lib/sysctl.d/*.conf /etc/sysctl.conf /etc/sysctl.d/*.conf`

Likewise in RHEL-08-040282, the check text specifies the same paths to verify `kernel.yama.ptrace_scope = 1`
> Check that the configuration files are present to enable this network parameter.
> `$ sudo grep -r kernel.yama.ptrace_scope /run/sysctl.d/*.conf /usr/local/lib/sysctl.d/*.conf /usr/lib/sysctl.d/*.conf /lib/sysctl.d/*.conf /etc/sysctl.conf /etc/sysctl.d/*.conf`

**From the above, we can see the following paths are missing from the SCAP Security Guide:**
- `/usr/lib/sysctl.d/`
- `/lib/sysctl.d/`

The result is the following two findings for RHEL-08-010671:
- `/usr/lib/sysctl.d/50-coredump.conf:kernel.core_pattern=|/usr/lib/systemd/systemd-coredump %P %u %g %s %t %c %h %e`
- `/lib/sysctl.d/50-coredump.conf:kernel.core_pattern=|/usr/lib/systemd/systemd-coredump %P %u %g %s %t %c %h %e`

And the following two findings for RHEL-08-040282:
- `/usr/lib/sysctl.d/10-default-yama-scope.conf:kernel.yama.ptrace_scope = 0`
- `/lib/sysctl.d/10-default-yama-scope.conf:kernel.yama.ptrace_scope = 0`

#### SCAP Security Guide Version:
- 0.1.72 (Feb 2024)

#### Operating System Version:
- RHEL 8 (confirmed)
- (Possibly RHEL 7 and 9?)
