[libvirt] [PATCH] build: silence compiler warning about signedness

[Eric Blake]

Commit 246143b fixed a warning on older gcc, but caused a warning
on newer gcc.

../../src/rpc/virnetserverservice.c: In function 'virNetServerServiceNewPostExecRestart':
../../src/rpc/virnetserverservice.c:277:41: error: pointer targets in passing argument 3 of 'virJSONValueObjectGetNumberUint' differ in signedness [-Werror=pointer-sign]

* src/rpc/virnetserverservice.c: Use correct types.
---

Pushing under the build-breaker rule, again.  Gah - sometimes I need to
slow down and test patches on more than one machine before pushing.
Sorry for today's churn.
