protobuf: fix deps problem, allow disabling install

* Now dependency from abseil is correctly carried to 'upstream' project
  when building protobuf as subproject
* Allow disabling installation. This patch adds new option
  'should_install' and uses it as value for 'install' argument
  in all appropriate meson invocation. The intended use is to disable
  installing protobuf when it is bundled as subproject.
