fix(lib): sudo-{find,this}-file: disable auto-save

Browse source 
auto-save can trigger processes that hang silently in the background,
making those buffers inoperable (hanging Emacs) for the rest of the
session, even if they are killed (tramp caches them), so I suppress them
solely for these temporary tramp buffers created by doom/sudo-find-file
and doom/sudo-this-file.
