submodules: cpp-httplib: Update

Any small change on a page "updates" the feed, which is misleading to clients.
May need "minor edit" or something. For now, get rid of it.

 The first three are header-only libraries that are included as a git submodule. The others must
 be installed, e. g. by using your distributions standard method.
