Cleanup sanitize build sed and sh scripts.

Minor cleanup:
* switch regexes to extended regexes,
  which remove a few gratuitous backslashes
  (and makes them less confusing, since basic regexes are so rarely used)
* fix . -> \. (which *does* need escaping in either case)
* make sed files non-executable,
  since if executed they just say "don't execute this"
* delete blank line

(Just noticed these scripts when working on Blink IDL bindings, and made
 necessary fixes for my changes, but cleaning up while I'm here.)
