Fix format specifiers in test cases on Win32

Browse Source 
Some of the test suites use fprintf with format specifiers
that are not supported on Win32 and are not fixed by gnulib.

The mingw32 compiler also has trouble detecting ssize_t
correctly, complaining that 'ssize_t' does not match
'signed size_t' (which it expects for %zd). Force the
cast to size_t to avoid this problem

* tests/testutils.c, tests/testutils.h: Fix printf
  annotation on virTestResult. Use virVasprintf
  instead of vfprintf
* tests/virhashtest.c: Use VIR_WARN instead of fprintf(stderr).
  Cast to size_t to avoid mingw32 compiler bug
