Updated Linux scripts to remove custom libpng/zlib as it's fixed in wxwidgets.

Disable debugging termination when stack trace received from remote process.

It's not always desired to kill the remote process, which this termination
leads to. For example, Corona SDK displays an error message in the
Simulator and terminating the debugging, kills the simulator, which makes
it difficult to see the error message.
