[PATCH 1/2] test: Rename propagating signal handler

[David Gibson <david@gibson.dropbear.id.au>]

nstool in "exec" mode will propagate some signals (specifically SIGTERM) to
the process in the namespace it executes.  The signal handler which
accomplishes this is called simply sig_handler().  However, it turns out
we're going to need some other signal handlers, so rename this to the more
specific sig_propagate().
