Use /usr/lib/os-release and /etc/os-release

### Describe the bug.

Make sure your program can skin a cat multiple ways! Look for it in both places and new users will be able to actually install the thing.

The file /etc/os-release takes precedence over /usr/lib/os-release. Applications should check for the former, and exclusively use its data if it exists, and only fall back to /usr/lib/os-release if it is missing. Applications should not read data from both files at the same time. /usr/lib/os-release is the recommended place to store OS release information as part of vendor trees. /etc/os-release should be a relative symlink to /usr/lib/os-release, to provide compatibility with applications only looking at /etc.

### Please attach log file(s) here if you have any.

Gen X doesn't need log files. ;-)

### Reproduction Steps

Remove os-release file @ /etc/os-release and/or break sim link to /usr/lib/os-release. This is to make it act like this info didn't get placed correctly.

### Expected Behavior

Microsoft employees to test their code!
