Restore msgbox_mask package defaults (#2527)

Updates DR to
[a15656a0c](36a6d23).
Replaces the AUTOMATED_TESTING set in package builds by PR #2474 with
the new DISABLE_ZLIB CMake option added by
DynamoRIO/dynamorio#7030. This fixes a regression where msgbox_mask was
set to 0 by default in packages, which caused many users to fail to
obtain error information and has led to confusion with silent errors.

Tested:
Built
https://github.com/DynamoRIO/drmemory/releases/tag/cronbuild-2.6.20005,
unzipped it, and confirmed it pops up a message box by default on the
machine where DynamoRIO/dynamorio#7024 is hit.

Fixes DynamoRIO/dynamorio#7025
