Reenable GrAAHairlinePathRenderer assert w/ fix

r11365 ("Fix" for hairline corner bugs - https://codereview.chromium.org/23708036/) altered the hairline line geometry but didn't update the outset on the device space bounding box. Since line caps are now added the outset needs to be a little larger.

Why did this get removed? Is it unnecessary?

devBounds is actually uninitialized at this point so the outset is just
outsetting garbage. The set (down below at line 762) actually overwrites the
outset garbage.

It's unclear why it's sqrt(1.25) -- maybe expand to sqrt(1^2 + 0.5^2)?

Done.
