I got bit in a debugging session on an uninstalled libvirtd; the
code tried to call out to the installed $LIBEXECDIR/libvirt_iohelper
instead of my just-built version. So I set a breakpoint and altered
the binary name to be "./src/libvirt_iohelper", and it still failed
because I don't have "." on my PATH.
According to POSIX, execvp only searches PATH if the name does
not contain a slash. Since we are trying to mimic that behavior,
an anchored name should be relative to the current working dir.
* src/util/util.c (virFindFileInPath): Anchored relative names do
not invoke a PATH search.
