pipewire,remoting,tests: Replace asprintf w/ str_printf
We have a string helper which wraps asprintf(). Uses that one because it clears out the destination string, but also it won't return the number of bytes unlinke asprintf().
Fixes warnings like: warning: ignoring return value of ‘asprintf’ declared with attribute ‘warn_unused_result’.
