llvm*: Remove outputSpecified workaround where possible

The effect of `.out // { outputSpecified = false; }` in these cases
is to select the default output explicitly, but then make the
selection implicit until `overrideAttrs` is called. Previously
`overrideAttrs` would not preserve output selection, masking the
apparently unnecessary behavior of this workaround.

For `libllvm-polly`, this logic does not apply, as it does not
select the default output.

The `outputSpecified` workaround was introduced in
#122554

and was perhaps rushed because of a release deadline, and expected
delays from mass rebuilds.

The change in `overrideAttrs` behavior was added in
5b2f597 / #211685

and the problem was discovered in #218537,
which may contain further information.
