[Libosinfo] [PATCH] force a UTF-8 locale for python3 to avoid broken ascii codec

[Daniel P. Berrangé]

The python3 ascii codec violates POSIX C locale requirements by not being
8-bit clean in its text handling. It raises an error for any byte with
top bit set

  >       return codecs.ascii_decode(input, self.errors)[0]
  E       UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 419: ordinal not in range(128)

To avoid this python bug we must force use of a UTF-8 locale. Ideally we
would use the C.UTF-8 locale, however, that is not portable across OS,
only existing on certain Linux distros. Instead we use the en_us.UTF-8
locale, but only for the character set data.
