[PATCH] ModemManager: handle "change" uevents as well as "add"

[Nathan Williams <njw google com>]

The udev strategy used by ModemManager, as expressed in
80-mm-candidate.rules, expects "add" events to be emitted at startup
when device rules have been processed (said events usually being
generated by "udevadm trigger"). However, since udev-152, "udevadm
trigger" generates "change" events instead. It's possible for distros
or startup scripts to work around this, but I suggest we should just
go ahead and accept these events as-is.

Subject: [PATCH] handle_uevent(): Handle "change" events as well as "add", since that's
 what the udev replay gives us these days (as of udev-152).
