Add Amazon Linux support in installation script

[jggc]

Amazon Linux works well with the RPM package and using the rpm package
improves integration with the distribution. To do that I detect the
distribution name in /etc/system-release.

Also refactored the variables to be consistently using "${}" through the
script.
