Well the exact line is this:

  VDPAU_DRIVER=va_gl \
  LD_LIBRARY_PATH=$(./pre-inst-env guix build libvdpau-va-gl)/lib/vdpau \
  $(guix build vdpauinfo)/bin/vdpauinfo

Works for me!  It displays lots of things.  :-)

So I think you can push the package, and then we need to figure out what
to do on GuixSD with ‘VDPAU_DRIVER’ (set it unconditionally to ‘va_gl’?)
and how to avoid LD_LIBRARY_PATH.
