prefix test names with libva_

[okias]

The binary names could all be prefixed with libva or something like that. Ideally this would be fixed upstream first.

+/usr/bin/av1encode
+/usr/bin/avcenc
+/usr/bin/avcstreamoutdemo
+/usr/bin/h264encode
+/usr/bin/hevcencode
+/usr/bin/jpegenc
+/usr/bin/loadjpeg
+/usr/bin/mpeg2vaenc
+/usr/bin/mpeg2vldemo
+/usr/bin/putsurface
+/usr/bin/putsurface_wayland
+/usr/bin/sfcsample
+/usr/bin/vacopy
+/usr/bin/vavpp
+/usr/bin/vp8enc
+/usr/bin/vp9enc
+/usr/bin/vpp3dlut
+/usr/bin/vppblending
+/usr/bin/vppchromasitting
+/usr/bin/vppdenoise
+/usr/bin/vpphdr_tm
+/usr/bin/vppscaling_csc
+/usr/bin/vppscaling_n_out_usrptr
+/usr/bin/vppsharpness

I was talking about including tests inside the package, but these names are pretty generic, would be ok to prefix them with libva_ ?

it is a good idea, for distributions , it maybe some confusing about this binary,
from my understanding, maybe we need provide some options , such like
only install vainfo or install all samples.
I guess most people only use vainfo to check the capabilities

vainfo is currently only binary which Debian ships, but I find useful in case of troubleshooting (and our CI) to be able also install package with tests (but they shouldn't be that generic, so it won't collide with other possible packages)
