5906b1ad - [APINotes][test] Fix permissions of a file copied from a source tree

[APINotes][test] Fix permissions of a file copied from a source tree Our CI system makes the source tree read-only. The 'cp' command that copies a directory from the source tree into a temp directory preserves permissions, and the copied files stay read-only. When the test tries to append to one of these files, it fails with a "permission denied" error.
