Don't enable app shims in tests. (Mac)

This causes problems for try bots as the app shims cannot connect to
the test chrome processes. Also are created in user-local (rather than
test-local) locations.

BUG=334079

TEST=Tests that install apps (e.g.PlatformAppBrowserTest) should
not create app shims (in ~/Applications/Chromium Apps/).
