[lldb][test] Skip `array` test due to ASTImport lambda issue (#163735)

The test will fail if libc++ starts to use a lambda in `<array>`. This
will become the case because
- libc++'s `array::fill` uses `std::fill_n`, and
- `std::fill_n` is to be optimized for segment iterators, and
- the natural approach for such optimization uses lambdas.

Until ASTImport of `clang::LambdaExpr` nodes gets properly fix, this
will need to be skipped.
