[BlackBerry] browser video player fullscreen mode (portrait) - Controls are off screen so cannot exit fullscreen

PR #162991

Patch by Antonio Gomes <agomes@rim.com>

When we use width:100%/pageScale as the math to calculate the width of the
FullScreen element, it goes too wide for horizontally scrollable webpages.
The reason is that 100% is relative to the content size here, and we want 100%
relative to the viewport size. However, since there is no such a thing in CSS,
we set an absolute file.

A known problem with this will be rotating the device when in fullscreen mode
that we can address when rotating is supported.
