MMFMWK-7030 [Linux_MX6QP_ARD]IMXCameraApp:When Enabled "save time to image" item, preview, find the time can not display completely. 100%

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.

Upstream Status: Inappropriate [i.MX specific]
