Build fix: ipc_tests.exe is not getting built for Windows release.

(Broke in r21342)

<jamesr> agl: chromium XP release builder builds chrome.sln and then tries to
run ipc_tests.exe. nothing in chrome.gyp depends on ipc_tests now so the
executable doesn't exist on that builder
<jamesr> agl/jrg: adding a dependency on ../ipc/ipc.gyp:ipc_tests to the
'coverage' target would solve both issues
<jrg> jamesr: agl's change will only impact the coverage bots.  Sounds like
that't not what you want, right?
<jamesr> jrg: i think it's correct but won't resolve the chromium XP issue.
coverage should run for those tests either way
<agl> jamesr: how about I tie it to unit_tests?
<agl> jamesr: there's a long term solution and then there's getting the builder
green.
<jamesr> agl: yeah. trying to check super fast if getting that builder to not
run ipc_tests.exe is easy
