Make RC4 string-to-key more robust

krb5int_utf8cs_to_ucs2les() can read slightly beyond the end of the
input buffer if the buffer ends with an invalid UTF-8 sequence.  When
computing the RC4 string-to-key result, make a zero-terminated copy of
the input string and use krb5int_utf8s_to_ucs2les() instead.
