curses: do not initialize LC_ALL to user settings (issue6358)...

curses: do not initialize LC_ALL to user settings (issue6358) moved the setlocale() call to right before curses was used. This didn’t fully solve the problem it was supposed to solve (locale-dependent functions, like date formatting/parsing), but only postponed it. Initializing LC_CTYPE seems to be sufficient for curses to work correctly. Luckily this is already done at interpreter startup on modern Python versions and, since recently, by Mercurial in the pycompat module in all other cases.
