The generated static.go file was missing a license header when it was
created in 2013 in CL 12805046. CL 38165 added a license header, using
the current year in the template. This causes the static.go file to go
"out of date" whenever the year changes.
Change the copyright year to be a fixed year when the file was created.
This way, the TestStaticIsUpToDate test will stop breaking every year.
