[Libguestfs] [PATCH] daemon: Fix configure check so it requires hivex.

[Richard W.M. Jones]

Commit 4d3601eb4ed1e314a8d4944a09a7f81638396cb6 made it clear that
ocaml-hivex is required, implying also that hivex is required.
However the configure test was still optional, and if you built
libguestfs without hivex you got a very long and confusing error in
the daemon/ subdirectory.

Thanks: Cédric Bosdonnat
