localedata: LC_MESSAGES.{yes,no}expr: standardize yY/nN [BZ #15262]

The vast majority of languages include yY/nN in their yes/no regexes.
Standardize the few that were missing them.
  ms_MY: noexpr: add nN
  nan_TW@latin: yesexpr: add yY
  nan_TW@latin: noexpr: add nN
  se_NO: noexpr: add nN

This also highlighted a few that were incorrectly using yY/nN because
they clashed with their localized messages:
  uz_UZ: yesexpr: change ^[+1YyHh] to ^[+1ҲҳHh]
  uz_UZ: noexpr: change ^[-0JjNn] to ^[-0ЙйNnYyJj]
  uz_UZ@cyrillic: yesexpr: change ^[+1ҲҳYy] to ^[+1ҲҳHh]
  uz_UZ@cyrillic: noexpr: change ^[-0ЙйNn] to [-0ЙйNnYyJj]
  yo_NG: move nN (short for Bẹ́ẹ̀ni) from noexpr to yesexpr
