Gavin Lee 39a676c496 Correct license header mainly for patches folder
Signed-off-by: Chip Childers <chip.childers@gmail.com>
I've assumed that Gavin's commit is appropriate, based
on an assumption that we will keep these files in the source
tree.  If https://issues.apache.org/jira/browse/LEGAL-146
results in a different opionion from the members, then we
will end up having to do something more drastic anyway.
