Revert of Remove Mac10.11 specifiers from TestExpectations as an experiment. (patchset #1 id:1 of https://codereview.chromium.org/2106903002/ )

Reason for revert:
After this was committed, the webkit_tests on the waterfall went red (example build https://build.chromium.org/p/chromium.webkit/builders/WebKit%20Mac10.11/builds/7222)

This means that these lines in TestExpectations are *not* without effect.

Original issue's description:
> Remove Mac10.11 specifiers from TestExpectations as an experiment.
>
> Due to bug 624020, it seems possible that the Mac10.11 specifiers in TestExpectations have been ignored by the WebKit Mac 10.11 builder; if this is the case, then those specifiers in TestExpectations should have no effect and could theoretically be removed.
>
> Submitting this CL might cause WebKit Mac 10.11 to fail, and if that happens, then this should be reverted.
