localedata: standard LC_MESSAGES string regexes a bit

A few locales add .* to the end of regexes, but this isn't necessary.
Drop it to simplify things.  e.g. It goes from ^[yY].* to ^[yY].  Did
it for all these locales for yesexpr & noexpr:

A few locales were missing ^ anchors, so add them.  e.g. It goes from
[oOyY].* to ^[oOyY].
  fil_PH ik_CA iu_CA

Some locales are defining a subset of values when there are fuller ones
available (according to the language).  Switch them to copy instead.
