regcharclass.h: Remove 2 EBCDIC dependencies

This commit makes is_HANGUL_ED_utf8_safe() return 0 unconditionally on
EBCDIC platforms.  This means its callers don't have to care what
platform is running.  Change the two callers to take advantage of this

The commit also changes the description of the macro to be slightly more
accurate
