configure: libva-xyz should be same version as detected libva

This will help prevent erroneous linking to mixed versions
of libva-xyz window system libraries that may not be binary
compatible.  For example,
 1. User installs libva-dev from distro packages that
    provides all libva-xyz.pc/.so window system libraries.
 2. Then, user compiles and installs libva from source with 1
    or more [auto] disabled libva-xyz window system libraries.
 3. Finally, user compiles libva-utils from source, but configure
    finds a mix of distro installed and user compiled
    libva-xyz window system libraries and encounters linker
    error when not binary compatible with user installed
    libva.so.
