Baptiste Daroussin 473aa0b7ee locales: Enforce US-ASCII encoding (limited to 7-bit)
The US-ASCII format was getting treated identically to POSIX.  It is
supposed to throw an ILSEQ errno if a value of 0x80 or greater is
encountered, so let's bring back the "ASCII" handling.

While here, change nl_codeset to return US-ASCII only when the encoding
really is "US-ASCII".  Before "C" and "POSIX" encoding returned this
string, so now they return "POSIX".
