Andrew Deason d16a0f8d16 tests: Introduce afstest_asprintf
Add a thin wrapper around asprintf, called afstest_asprintf (and
afstest_vasprintf), which does its own error checking. This just helps
makes tests a little less cluttered when needing to construct strings.

Adapt all asprintf callers in 'tests' to use the wrapper.
