The recalls for that broken batch of Sony batteries dates back from
2006. All the batteries that could have been recalled have now
been recalled, and somebody particularly interested in supporting
them can match the batteries using the old rules file, in a
user session or a separate daemon.
Udev rules may live in either /lib/udev/rules.d or /usr/lib/udev/rules.d depending on the distro.
Remove the heuristic for deciding the dir, use pkgconfig to detect the location and allow it to be
set manually.
v2: fix specifying --with-udevrulesdir
