    lua-factory: Fix lua sources path with Meson
    
    lua-factory was trying to find lua sources in:
    ~/.local/share/share/grilo-plugins/grl-lua-factory
    amongst other directories with duplicated "share" components.
    
    luafactorydir is used to pass "LUA_FACTORY_SOURCE_LOCATION" as a define,
    but it has a value of "grilo-plugins/${LUA_FACTORY_PLUGIN_ID}" when
    using autotools, without a "datadir" component.
