expand-response-params: add description

Browse source 
Since the tool is exposed more prominently now, we should clear up what
it is and note that it is to be considered unstable, i.e. we may change
it if the necessity arises. (In practice it is probably going to be
fairly stable though, as compiler interfaces tend to be quite stable.)

Should we add a version?

longDescription = ''
expand-response-params is a tool that allows for obtaining a full list of all
arguments passed in a given compiler command line including those passed via
so-called response files. The nixpkgs wrapper scripts for bintools and C
compilers use it for processing compiler flags. As it is developed in
conjunction with the nixpkgs wrapper scripts, it should be considered as
unstable and subject to change.
