[Qemu-trivial] [PATCH] misc: Avoid UTF-8 in error messages

[Eric Blake]

While most developers are now using UTF-8 environments, it's
harder to guarantee that error messages will be output to
a multibyte locale. Rather than risking error messages that
get corrupted into mojibake when the user runs qemu in a
non-multibyte locale, let's stick to straight ASCII error
messages, rather than assuming that our use of UTF-8 in source
code string constants will work unchanged in other locales.
