Fix content property tests in css/css-page/margin-boxes/ for Mac.
Use the content property in the refs as well as in the test, to better
match what the tests do. Also set a fixed width in
content-001-print.html , because we cannot assume that the width of
"PASS" is the same as the width of "PA" "SS".
These test are currently only run as part of virtual/page-margin-boxes/
which is only run on Linux, so it wasn't detected when landing the
tests.
