fixed default rule for lib/Makefile

updated spec on dictID==0

Specified decoder behavior on receiving a frame with dictID=0.

Pushed paragraph on reserved DictID ranges into the Dictionary Format section.

default rule is `lib-release`

`lib-release` wasn't working : it was just skipped.

Removing `lib-release` from the list of .PHONY targets fixes it.

Same for `lib-mt`.

[pzstd] Fix compilation error in MinGW

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.

Fix legacy build after #2103
