uitest: make child soffice process die when parent dies

using PR_SET_PDEATHSIG.

Note that this can only be called by the child process in question, so
we have to pass a new command line argument down to activate it.

And we have to plumb it through the wrapper oosplash process.

I wonder where else our testing infrastructure could benefit from this
