Partial fix for PR 91106. Correct the short weekday names. Done according to this poll https://bugzilla.redhat.com/show_bug.cgi?id=242296. This will not close the bug fully yet, as the month names are still not correctly in Genitive. More research on this topic will be done, as I'm suspecting a bug in the libc locale functions picking the month name from the wrong group.

Invalid (long) date format in pl_PL.ISO8859-2.src

Date format is %a %e %b %X %Y %Z (e.g "sob 19 sty 15:46:50 2008 CET")
but should be "%a %e %b %Y %X %Z" (e.g. "sob 19 sty 2008 15:46:50 CET").

Comments fixing
1) Back out "month names" -> "months names" and fix few such cases which
are wrong initially
2) "weekdays names" -> "weekday names"

Noted by: des [1]

Comments fixing
"month names" -> "months names"
typo
"Long months names (alternative)" or "in alternative form" ->
"(without case ending)"
"Long months names" -> "Long months names (as in a date)"
to not confuse developers on what purpose those sections are

- Month and weekday names should begin with lowercase latter.
- First part of long month names should use genitive.
- Use more proper shortcuts, leaving the first 3 letters is not always
correct.

Add UTF-8 versions of all the currently supported system locales. Most of
the hard work was done by Hye-Shik Chang in the misc/utf8locale port; I made
a few minor adjustments and merged the makefiles.
