- 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.

Using the meta package causes several issues:
- Install on Debian prior to Jessie and Ubuntu prior to Xenial is broken, since those do not serve the meta packages but php5-* packages instead.
- If $phpVer != "php", then multiple conflicting PHP versions can be installed.
- If "${phpVer}-intl" does not pull the correct package, then inherently "${phpVer}-xml" etc are wrong, too. This is theoretically possible, e.g. if PHP7.4 was installed while the webserver uses a concurrently installed PHP7.3 instance. Then the "php" shell command output can differ from what the webserver uses. This theoretical issue would need a different approach to derive $phpVer, not based on the shell command output but by asking the webserver somehow in the first place. But using $phpVer for some modules and hardcoded meta for the others can only lead to inconsistencies and issues.

When checking for available packages in APT repository, running a dry-run install can fail for other reasons, even if the package is available. Currently, in such case, wrong fallback packages are selected: https://github.com/pi-hole/pi-hole/issues/2888
"apt-cache show <pkg>" is a quicker method to check for available packages. This is now done as well to check if the fallbacks are available. If none is found, the installer exits with meaningful error message and exit code.
In rare cases, the APT list files can be missing when the installer is started. E.g. this could be on a fresh system, APT lists could have been moved to RAM or removed as a cleanup step. "apt-cache" calls will then fail, same as dry-run installs were. To assure that current package lists are checked, update the package cache directly after the Ubuntu universe repo has been added, only in the Debian/Ubuntu block. This renders the variable handling in RH/Fedora block obsolete.
