pciaccess: properly detect and use

* configure.ac: Detect pciaccess pkg module. Define HAVE_LIBPCIACCESS,
libpciaccess_CFLAGS, libpciaccess_LIBS variables.
* config.make.in (HAVE_LIBPCIACCESS, libpciaccess_CFLAGS,
libpciaccess_LIBS): Add variables.
* Makefile (prog-subdirs) [!HAVE_LIBPCIACCESS]: Do not add pci-arbiter.
* pci-arbiter/Makefile (LDLIBS): Use $(libpciaccess_LIBS) instead of
-lpciaccess.
(CFLAGS): Use $(libpciaccess_CFLAGS).
