Fix wrong truncation of notification popup messages in ash.

Fix wrong truncation of notification popup messages in ash.

views::Label control first calculates the size of the text,
and then tries to render the text in the exact size of rectangle.
If < is used instead of <= in the patched line, the control
flows to the BreakIterator mode, that sometimes computes a
larger width value and causes truncation.

asvitkine@, according git-blame you looks to be the expert around here. Could
you take a look?

Sorry, I'm on vacation, please find a different reviewer.

Please add some test coverage.

Done--though it won't always catch the original issue; the problem is highly
font-dependent and I couldn't come up with a way to reproduce the same trouble
in arbitrary fonts.

Do you think this is sufficient?
(Besides, since Alexei is out, could you kindly be the primary reviewer of this
patch? If this is LG for you, I'll proceed to the CQ.)

If the unit test doesn't give coverage, nuke it. LGTM
