Fix incorrect SetupChooseLockPattern layout

Root cause:
- The new added description TextView is too large
- sud_layout_description was add in sud_layout_content
  instead of sud_layout_header.

Solution:
- Set string lockpassword_choose_your_pattern_description
  to GlifLayout as it's description.(Header description)
