Update SLE15 public cloud profiles

[jgleissner]

Description:

This PR makes the following changes to the SLE15 profiles:

• Drop smartcard related rules
• Drop mount_option_dev_shm_noexec from SAP profile
• Add profile for CHOST hardening

Rationale:

• Public cloud VMs do not have smartcard readers so smartcard related rules in the public cloud profiles are pointless
• mount_option_dev_shm_noexec seems to expect /dev/shm being mounted via /etc/fstab which is not the case in SLES so seems incompatible
• For SLES instances that are optimized as container host we need a STIG based profile

Hi @jgleissner. Thanks for your PR.

I'm waiting for a ComplianceAsCode member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
