Put cpp config file to ~/.emacs.d/cpp.el if possible (Bug#28685)

Browse source 
If `cpp-config-file` starts with '.', remove the '.'
when putting the file to ~/.emacs.d.
Suggested by Noam Postavsky <npostavs@users.sourceforge.net>

* lisp/progmodes/cpp.el (cpp-locate-user-emacs-file): New
function wrapping `locate-user-emacs-file`.
(cpp-edit-load, cpp-edit-save): Use it.
