Richard Purdie 7350e82ce1 scripts: Add copyright statements to files without one

Where there isn't a copyright statement, add one to make it explicit.
Also drop editor config lines where they were present and add license
identifiers as MIT if there isn't one.

(From OE-Core rev: deb3ccec53e0bd63bc4235cf2b0d3fc781687361)
