There's already a copyright notice in <sys/pagesize.h>.  Other very
short bits/ headers do not have copyright notices, either, so I didn't
think one was necessary here.

Sharing files is hard.  We could set the default at 4 KiB pages (only),
which would avoid the need for some files, but we then lose the reminder
to new port authors that they need to think about future page size
ranges, especially if there are no test failures because the initial
test system has 4 KiB pages.

Thanks,
Florian
