Revert using hardcoded php-intl meta package

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.
