[libvirt] [PATCH] build: fix building with '--enable-test-locking'

[Martin Kletzander]

When test-locking is enabled, CFLAGS have -Dbool=char, which makes
pipefd[bool] fail (obviously).  Forcing the subscript to be bool by
double negation fixes the build breaker.

Notes:
    I still can't build with '--enable-test-locking' and I'm not sure this
    is the proper way to fix it.  Also, the code wasn't touched for
    months, so I'm not pushing it as a build-breaker.
