Subject: doc: avoid needless rebuilds of NEWS

Repeatedly rebuilding `NEWS' because the mtime of `NEWS'
is synched to the latest release .eml is a bit annoying,
but necessary to save bandwidth for the website.

So we'll also update the mtime of the source .eml file when
reading them.  It's kinda gross to be setting mtimes of source
.eml files in Documentation/RelNotes/, but I can't think of
anything better at the moment...
