[libvirt] [PATCH] build: fix 32-bit test failure

[Eric Blake]

ARRAY_CARDINALITY is typed as size_t, not long; this matters on 32-bit
platforms:

hashtest.c: In function 'testHashRemoveForEach':
hashtest.c:114: error: format '%lu' expects type 'long unsigned int', but argument 4 has type 'unsigned int' [-Wformat]

* tests/hashtest.c (testHashRemoveForEach): Use correct format.
---

Pushing under the build-breaker rule.
