stdio-common: Add tests for formatted vasprintf output specifiers

Wire vasprintf into test infrastructure for formatted printf output
specifiers.

Owing to mtrace logging these tests take amounts of time to complete
similar to those of corresponding asprintf tests, so set timeouts for
the tests accordingly, with a global default for all the vasprintf
tests, and then individual higher settings for double and long double
tests each.
