ContainerFactory hardcodes some directories to /var/… about installation-bundle

[fritzmg]

Another problem occurs when the InstallationController generates the bootstrap.php.cache file here. The cache directory is hardcoded to /var/cache: ContainerFactory.php#L52 - thus the new bootstrap.php.cache file will be generated in /var instead.

And if you try to go to example.org/contao/install afterwards, you'll see the following error message multiple times:

Warning: file_get_contents(/var/www/contao4test/htdocs/app/bootstrap.php.cache): failed to open stream:
No such file or directory in /var/www/contao4test/htdocs/vendor/symfony/symfony/src/Symfony/Component/ClassLoader/ClassCollectionLoader.php on line 153

Which is weird, because the old bootstrap.php.cache definitely still exists in that location.

Reproduction (basically the same as above):

1. Install Contao 4.2.5 via composer create-project contao/standard-edition <target> 4.2.5.
2. Open example.org/install.php.
3. Update the installation to Contao 4.3.0 via composer update.
4. Open example.org/install.php.

The aforementioned Warnings will be shown.

Running

composer run-script post-update-cmd

does not fix it. If you delete /app/cache/*, the following errors will be shown:

Warning: require(/var/www/contao4test/htdocs/app/../../../../../vendor/symfony/symfony/src/Symfony/Component/ClassLoader/ClassCollectionLoader.php): failed to open stream: No such file or directory in /var/www/contao4test/htdocs/app/bootstrap.php.cache on line 4

Fatal error: require(): Failed opening required '/var/www/contao4test/htdocs/app/../../../../../vendor/symfony/symfony/src/Symfony/Component/ClassLoader/ClassCollectionLoader.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/contao4test/htdocs/app/bootstrap.php.cache on line 4

I can confirm this. Tested this on two different linux machines.

We need to use $cacheDir = $kernel->getCacheDir() and $logsDir = $kernel->getLogsDir().
