cmake:

* Don't use dyld functions on darwin by default as they are deprecated.
* Defines HAVE_DYNAMIC_MODULES, and add an entry in the options for it.
* Fix config.h generation (was accidentaly removed).
* Fix FindDlopen.cmake
This produce a working in tree vlc AND an installable vlc at the same time.
