Philipp Rudo f7430027b4 zipl/libc: Replace sprintf with snprintf ...

The use of sprintf can easily result in buffer overflows as it assumes
that the buffer it writes to is large enough to contain the formatted
string. Thus replace sprintf by snprintf and update its users.

This removes the last user of vsprintf. Thus also remove vsprintf and
its dependencies.
