Only check SELinux states if "getenforce" command exists

- Currently, if the SELinux config file exists, installed SELinux is assumed.
- But removing e.g. an APT package via "apt-get remove" leaves config files in place, or they could be present for other reasons.
- If the getenforce command is not present but the config file is, currently the installer exists without error message when calling getenforce due to "set -e".
- With this change, the presence of getenforce command is checked first. If it is not present, selinux-utils is not installed, which is a core part of SELinux, pulled in by selinux-basics as well. So it can be assumed that no SELinux is active if this command is missing.
