iotests: vmdk: Enable zeroed_grained=on by default
In order to avoid bitrot in the zero cluster code in VMDK, enable
zeroed_grain=on by default for the tests.
059 now unsets the default options because zeroed_grain=on works only
with some subformats and the test case tests many different subformats,
including those for which it doesn't work.
