libdrm: also install modeprint and proptest tests

[HiassofT]

These test programs are already built but haven't been included in image yet.

They are quite handy when testing drm stuff and only add about 40k (uncompressed) to the image

I'm fine with this although I never added them before because I always thought they we rather clunky to use and may only be needed very rarely, in which case I would just copy the binary over to test.

I've been using modetest before but recently found out that modeprint is really handy at times on RPi(4) as it doesn't spam me with the bazillion planes info which often I'm not too interested in - and if I forget to pipe output through less the scrollback buffer of my terminal is full of plane info. Same goes for proptest

LibreELEC:~ # modetest -M vc4 -c -p | wc -l
1933
LibreELEC:~ # modeprint vc4 | wc -l
112
LibreELEC:~ # proptest -M vc4 | wc -l
158

meh. modetest can do what the others already do (and more) so there really isn't any reason to add them IMO. If you can't pipe the output isn't really a valid reason to add them 😄

When I was developing the entire drm/gbm system for kodi I only ever needed modetest

shouldn't we add those stuff in a dev addon or similar ?
adding stuff that "nobody" needs besides at dev stage ? or maybe just add if the image is a dev image ?

@HiassofT is this PR still needed? .. support seems to have evolved some way since the original submission date. If still useful then the PR needs a rebase :)

also just noticed that it targets LE10 branch, not master.

I hadn't used these tools since then so let's just close the PR
