[virt-viewer] Don't use C99 for loops

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

Declaring a local variable as part as a for loop
such as 'for (unsigned int i; i < N; i++)' is a C99 specific feature.
Running configure with --enable-compile-warnings=minimal does not add
-std=c99 to the compile flags, so it's better if the codebase does not
require C99 support from the compiler.
