clang-format: Disable alignment of operands, too unreliable

Sets `AlignOperands` to `DontAlign`.

`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.
