do not install zbuff.h

this API is deprecated, for a loong time now,
all related symbols will be removed in a future version (likely v1.5.0)
and the header file `zbuff.h` doesn't compile from `include/` anyway,
because it needs to be positioned one directory below `zstd.h`.

Also removed `cover.h` from `cmake` installer,
as it should have never been part of this list to begin with.
