[libvirt] [PATCH] Use AC_PATH_PROG to search for dmidecode

[Roman Bogorodskiy]

This is useful in certain circumstances, for example when
libvirtd is being executed by FreeBSD rc script, it cannot find
dmidecode installed from FreeBSD ports because it doesn't have
/usr/local (default prefix for ports) in PATH.
