stubdom: Fix stubdom-dm using "grep" improperly

stubdom-dm uses "grep" on "xm list" output to determine whether it is
already running. The existing behavior is to use "grep $domname-dm"
but this will result in a false-positive in the case of another domU
running whose name ends with the full new name; for instance, if
"abctest-dm" is running, a new "test-dm" will spin forever, waiting
for it the end.

Any easy fix is to have it use "grep -w" instead of "grep", searching
for the whole word only.

It also might be worth considering a switch to "xl list" from "xm
list", here and in other places.
