= httpx: unwrap `MalformedContent` error in `ResponseTransformation`

When unmarshalling in the pipeline, MalformedContent exceptions were
converted to strings and set as the message for a PipelineException.
However, this suppresses the stacktrace of the underlying cause (if
there is one), making debugging a custom/delegate unmarshaller very
difficult.

This commit sets the cause of the PipelineException to that of the
MalformedContent exception (or null if it does not exist).

= util: remove unnecessary reflection in regex

Rather than reflecting on the pattern to get at the `capturingGroupCount` field (which does not exist on android and makes the routes blow up) we take the pattern and do a dummy match against an empty string, getting the `groupCount` from the result.

All the spray-routing tests passed, and trying it out in the console, the new snippet seems to do what I want. It also made my spray-on-android attempt get further in the boot process before blowing up on something else, so it solved my initial problem.
