mk: fix external shared library dependencies of libraries
    
    Similar to commit 5f9115e58cc6f304ff4ade694cf5823d32887d1a etc, but
    for libraries. Clean up librte_vhost CFLAGS/LDFLAGS/LDLIBS confusion
    while at it.
    
    Requiring applications to know about library internal details like
    dependencies to external helper libraries is a limitation of
    static linkage, shared libraries should always know their own
    dependencies for sane operation.
    
    Linking with the combined library (whether shared or not) still
    requires knowing the internal dependencies, and intra-dpdk
    dependencies are also not currently recorded.
