test-serve: fix test for binding to low named port on solaris
Solaris do not know the service called http, so we use echo instead.
Trying to define KILLQUIETLY when running the hgserve function didn't set the
value within the function. Now we set the variable before calling the function.
$ hg init
$ echo "nothing" > a
$ hg add a
$ hg commit -m ancestor
$ echo "something" > a
$ hg commit -m branch1
$ hg co 0
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ echo "something else" > a
$ hg commit -m branch2
created new head
$ hg merge 1
