Subject: [PATCH] MDL-70631 files: Replace hard-coded value with FL_ENC_RAW
 constant

This is not related to the issue but I noticed it while trying to debug
it.

Back when this line was introduced in 9c140a681e9, the ZipArchive had
not yet exposed this flag as a constant. It was added later with PHP
7.0.8 and we can switch to using it now.
