Cygwin: introduce /proc/codesets and /proc/locales

So far locale(1) had to have knowledge how to construct, thus
duplicating the effort how Cygwin handles locale strings.

Move locale list and codeset list generation into Cygwin by
providing /proc/codesets and /proc/locales files.  /proc/locales
does not list aliases, those are still handled in locale(1).

locale(1) opens the files and ueses that info for printing,
like any other application can do now.
