The root cause flaw is that non-root libvirtd is using /etc/libvirt for
its hooks. Traditionally that has been harmless though since we checked
whether we could access the hook file and degraded gracefully. We need
the same access check for iterating over the hook directory.
Long term we should make it possible to have an unprivileged hook dir
under $HOME.

This failed syntax-check:
../src/util/virhook.c:175: if (access(dir_path, X_OK | R_OK) < 0) {
../src/util/virhook.c:425: if (access(dir_path, X_OK | R_OK) < 0)
build-aux/syntax-check.mk: use virFileIsExecutable instead of access(,X_OK)
make: *** [../build-aux/syntax-check.mk:400: sc_prohibit_access_xok] Error 1
make: *** Waiting for unfinished jobs....
Given that this didn't break any tests and I believe we want this for the
upcoming release, feel free to change it to make 'syntax-check' happy and
add my r-b:
