This change modifies the chmod bits of build context archives built on windows to preserve the execute bit and remove the r/w bits from grp/others. Also adjusted integ-cli tests to verify permissions based on the platform the tests are running. Fixes #11047. Signed-off-by: Ahmet Alp Balkan <ahmetalpbalkan@gmail.com>
