[PATCH 2/3] virdnsmasq: Lookup DNSMASQ in PATH

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

While it's true that our virCommand subsystem is happy with
non-absolute paths, the dnsmasq capability code is not. For
instance, it does call stat() over the binary to learn its mtime
(and thus decide whether capabilities need to be fetched again or
not).

Therefore, when constructing the capabilities structure look up
the binary path. If DNSMASQ already contains an absolute path
then it is returned (and virFindFileInPath() is a NOP).
