package/petitboot: prefer UTF-8 support

Browse Source 
The petitboot UI looks much nicer in a Unicode locale:

* Items in the language selection submenu use multibyte Unicode
  characters. In other locales, they say "Unable to display text in this
  locale".

* The combination of TERM=linux with a UTF-8 locale is required to
  trigger a special-case workaround in ncurses code[1]. Without
  this, line-drawing characters in the menu look like q's.

Turn on wchar support in ncurses, and add a reminder that a UTF-8 locale
should be generated for things to look right.

is one listed in BR2_GENERATE_LOCALE.
