Pass -debug flag to runsc.
As of commit 3f053259, gVisor sentry panics are no longer sent to the
stderr for "runsc run" by default, as that stderr belongs exclusively to
the application.
As a result, syzbot never sees the gVisor panic stack trace, and is only
reporting errors that occur when waiting for a dead sandbox.
Passing the "-debug" flag to runsc will make the sentry panics visible
to syzbot again.
