Subject: scripts: always use printf with embedded gettext

This addresses two problems:

1) echo's behavior is inconsistent when dealing with flags, and can
potentially be problematic.

  $ echo -n
  $ echo -- -n
  -- -n

2) Always using the end of options markers prevents translated strings
from throwing errors, as shown in FS#28069.

The remaining "inconsistencies" are because printf is being used in a
guaranteed safe manner, e.g.

  printf '%s\n' "$(gettext "--this can never break")"
