Philipp Rudo 454f1427d3 zipl/libc: Fix printing zeros in vsnprintf ...

Printing the number zero (e.g. printf("%u", 0)) currently only gives you
an empty string. This is because the while-do loop to map the number to a
string is only entered when the value is 'true', i.e. non-zero. Fix this
by using do-while instead.
