[PATCH] uml: workaround old problematic sed behaviour

Old versions of sed from 1998 (predating the first release of gcc 2.95, but
still in use by debian stable) don't understand the single-line version of the
sed append command.  Since newer versions of sed still understand the...
ahem, "vintage" form of the command, change our code to use that.
