pgsql: Add "SHIFT_JIS" as an accepted encoding name for locale checking

Add "SHIFT_JIS" as an accepted encoding name for locale checking.

When locale is "ja_JP.SJIS", nl_langinfo(CODESET) returns "SHIFT_JIS"
on some platforms, at least on RedHat Linux. So the encoding/locale
match table (encoding_match_list) needs the entry. Otherwise client
encoding is set to SQL_ASCII.

Back patch to all supported branches.
