[libvirt] [PATCH] build: avoid build failure without polkit

[Eric Blake]

rpmbuild of mingw-libvirt.spec failed with:

  GEN      libvirt.syms
  GEN      libvirt_qemu.def
cat: libvirt_access.syms: No such file or directory
cat: libvirt_access_qemu.syms: No such file or directory
cat: libvirt_access_lxc.syms: No such file or directory

I traced this to unconditionally trying to use the ACL .syms files,
even when polkit isn't in use.

build: avoid build failure without polkit
* src/Makefile.am (USED_SYM_FILES): Mark access driver symbols
according to use.
---

Even though this fixes a build-breaker (./autobuild.sh), I'm
reluctant to push this without review.  In particular, I'm worried
that I may need a v2 that further conditionalizes whether
libvirt_access_qemu.syms is sometimes omitted based on rpm arguments,
even if libvirt_access.syms is present.
