Contents of installed.php should be more deterministic

[ondrejmirtes]

PHPStan's result cache relies on installed.php contents to stay the same if the installed packages are the same.

If the contents of installed.php change to convey the same information, PHPStan's result cache is invalidated. Which isn't a big issue, but I guess the fix should be easy enough.

The specific thing that changed between installations with the same lock file is:

*** 1145,1156 ****
          'psr/log-implementation' => 
          array (
            'dev_requirement' => false,
            'provided' => 
            array (
!             0 => '1.0.0',
!             1 => '1.0|2.0',
            ),
          ),
          'psr/simple-cache' => 
          array (
            'pretty_version' => '1.0.1',
--- 1145,1156 ----
          'psr/log-implementation' => 
          array (
            'dev_requirement' => false,
            'provided' => 
            array (
!             0 => '1.0|2.0',
!             1 => '1.0.0',
            ),
          ),
          'psr/simple-cache' => 
          array (
            'pretty_version' => '1.0.1',

So the order of versions in provided key. I guess they should be ordered before exporting.

Maybe just a ksortRecursive here?
