[libvirt] [PATCH] build: fix build without HAVE_CAPNG

[Eric Blake]

Otherwise, a build may fail with:

lxc/lxc_conatiner.c: In function 'lxcContainerDropCapabilities':
lxc/lxc_container.c:1662:46: error: unused parameter 'keepReboot' [-Werror=unused-parameter]

* src/lxc/lxc_container.c (lxcContainerDropCapabilities): Mark
parameter unused.
---

Pushing under the build-breaker rule.
