Change boxSizingReliable test value to false in all IE versions.
Modify support comments to argument getComputedStyle guards
with oldIE support and not node.js which is not supported in 1.x.

Closes gh-1498

Android 2.3 is happy with returnValue already used for oldIE;
the getPreventDefault() fallback is not needed.

Half a minute is more than enough for the test to finish even in the slowest
browsers and in case of starving the PHP FPM process pool, one has to wait
for only half a minute to try again.

(cherry-picked from a10aa3aa)

Android 2.3 doesn't support stopImmediatePropagation; jQuery fallbacks
to stopPropagation in such a case.

PHP sleep function accepts time in seconds, not milliseconds; the previous
value was starving the PHP FPM process pool.

The "document ready when jQuery loaded asynchronously" test fails all the time
in iOS7 and sometimes in other browsers. Bumping the timeouts *might* help
these other browsers to be less flakey here.
