[Buildroot] [git commit] package/nvidia-driver: fixup libraries according to README

[Arnout Vandecappelle (Essensium/Mind)]

commit: https://git.buildroot.net/buildroot/commit/?id=9cda982855315d683d4880e6bb2a129133ea7213
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Create a symlink for libglx.so and drop libnvidia-wfb.so (aka libwfb.so)
since all selectable xserver versions in Buildroot provide their own.

VDPAU libraries should be installed into /usr/lib/vdpau/

https://download.nvidia.com/XFree86/Linux-x86_64/390.67/README/installedcomponents.html

Also, allow specifying target subdirectory per library and respect it in
the install loop.
