context: add library.use-fallback option

Browse source 
Normally, when loading a plugin feature, often a library.name property
is given as well. If the feature to load is not explicitly listed in
context.spa-libs, the library.name is used a fallback library.

Add an option to ignore this library.name and only use the
context.spa-libs entries. This makes it possible to only load explicitly
listed features in the config file and makes it possible to lock down
what plugins can be loaded.

Set the option to true by default for now, which keeps the existing
behaviour of using the fallback library. Add some more entries to the
context.spa-libs in case the option is switched off to make things
work.

Set the option to false for the minimal.conf.
