tex-hyperxmp{,-doc}: update to 5.11

Since the previous release, hyperxmp has fixed a handful of bugs and
incorporated the following two modifications.  First, hyperxmp disables itself
if LaTeX3 document metadata is available.  (Document metadata implies the
presence of PDF management, which completely breaks hyperxmp.)  Second,
hyperxmp uses \thetotalpages to compute the page count in an engine-independent
manner.
