Hans Erasmus 2bd4f146b5 Accommodate upcoming php 7.3 change (#12180)
* Accommodate upcoming php 7.3 change

An announcement on Twitter as well as [this](https://github.com/librenms/librenms/pull/12118) says future release will depend on PHP7.3 minimum. CentOS 8 ships with 7.2 by default. Also, the composer package's availability via `dnf` was dropped somewhere by CentOS project, so one needs to install it "manually" nowadays. I have yet to find a different solution than the one showed here. Any inputs welcome.

* Removed the dnf list command

* Made manual composer install the fallback method

* Fixed minimum PHP version.
