libvamp: Fix linkage against dl for hostsdk library.

Browse Source 
src/vamp-hostsdk/PluginLoader.cpp uses the dlopen function. On some platforms
you have to link against dl for this function. configure checks for dlopen
and adds -ldl to LIBS if you have to link against dl. We need to pass this
LIBS variable when linking the hostsdk library.
