gstreamer1.0-plugins-base: Fix IMXCameraApp image time cannot display issue.

IMXCameraApp: When Enabled "save time to image" item, preview,
find the time can not display completely.

As IPU need 8 pixels alignment, add one workaround in base text overlay
to generate 8 pixels alignment text video buffer. The side effect should
cause all text a little smaller.
