Bug#796329: dependencies are also needed

[Ferenc Wagner]

Actually, what I suggested above is not enough, these
/lib/multipath/*.so files occasionally require other shared libraries,
like libaio.so.1 in the case of /lib/multipath/libcheckdirectio.so.  I'm
not sure what's the best way to chase down these, but it's already done
for executables, so support is already there somewhere.
