The returned data is in US-ASCII (or else Latin-1), and resides in
consecutive memory. We can therefore return it in a QLatin1String,
which, however, will in general not be NUL-terminated.
Many users use the return value as part of a QStringBuilder
expression, and those which are not are not pessimized further by
this change.
The caller in qtimezoneprivate_icu looks as if it could simply zero
-terminate the return value and use it as-is, as opposed to
converting to UTF-8, but I left the code equivalent to the original
just the same.
