build: new option to build plugins within the daemon binary

Instead of creating libmm-plugin* and libmm-shared* libraries that are
dlopen()-ed on runtime, allow incorporating all plugins into the
daemon binary itself.

This makes the startup of the daemon much faster and also avoids
issues with builds that require linker namespace isolation.
