Fix hyphen-locale.html and hyphenate-limit-lines.html.

Fix hyphen-locale.html and hyphenate-limit-lines.html.
Even though I have implemented hyphenation for DumpRenderTree, a couple of layout tests still fail on Chromium DumpRenderTree due to the following reasons:
* hyphen-locale.html uses "en" and "en_GB" for the hyphenation locale, and;
* hyphenate-limit-lines.html uses capitalized words.
To fix these tests, this change supports these locales and capitalized words.

BUG=140490
TEST=hyphen-locale.html and hyphenate-limit-lines.html
