agetty: Fix input of non-ASCII characters in get_logname()
As login supports non-ASCII characters in the logname, agetty should be
consistent.
8b58ffdd
re-activated old and ASCII-only get_logname(), which restricted
the input to ASCII only. As the code does not read whole characters,
isascii(ascval) and isprint(ascval) returns nonsenses after entering a
non-ASCII character.
As keyboard maps don't contain unprintable non-control characters, it
seems to be relatively safe to remove both checks.
