Do not deploy executables

We do not need the files a2enmod, a2dismod, a2ensite, a2dissite because
we do not use the sites-available/ etc. directories and have a write-
protected file system.
Do not use apache2::mod_* recipes

We do not need them and we do not have the scripts available that these
commands use. Thus, disable all calls to the apache2::mod_* recipes.
Do not remove Includes directory

The apache2 cookbook wants to remove the files in there, but we do use
them.
