compat: initialize LC_CTYPE locale on all Python versions and platforms

Previously, the LC_CTYPE locale was not initialized according to user settings
on all Python versions (e.g. never on Python 2) and platforms (e.g. not on
some Python < 3.8 on Windows).

This broke e.g. non-ASCII filenames passed to the Subversion bindings on Python
2, resulting in error messages like "file:///tmp/a%C3%A4 does not look like a
Subversion repository to libsvn version 1.14.0".

The following command could be used to test this functionality. Adding it to the
test suite would be pointless, as the locale is always set to "C" during test
runs.

@command(b'check_initial_codeset', norepo=True)
def check_initial_codeset(ui):
    codeset1 = locale.nl_langinfo(locale.CODESET)
    locale.setlocale(locale.LC_ALL, '')
    codeset2 = locale.nl_langinfo(locale.CODESET)
    assert codeset1 == codeset2
