Unwind information fix for the vsyscall DSO

[Daniel Jacobowitz]

When working on GDB support I found a typo.  I assume the comment is
correct.  If you step to this particular instruction and backtrace, GDB gets
lost.

I haven't tested the fixed version yet, but I'm pretty confident in this
patch :-)  Please apply.
