When the ModemManager daemon is started by the init script, we're
explicitly calling mm_report_events_from_cache() so that all the
hotplug events that happened before that moment are properly notified
to the newly launched daemon.
This initial reporting of events does a wait for the ModemManager
process to be available in DBus, and if the daemon isn't registered in
the bus in a given time, the process is considered failed:

Update the default wait time for this initial event notification from
10s to 60s, because there are cases where the daemon is slower to
boot, e.g. during the first boot after a sysupgrade.

When a USB modem device is unplugged, we had to do two different
things: first, cleanup the sysfs cache; and second, set interface as
unavailable.
Those two things were never being done properly due to several
different issues:
* The parent sysfs path retrieval logic relies on checking for which
sysfs path has the vid/pid files. This logic obviously only works
when the device is available, and cannot be used on e.g. removal
events.
* The command to cleanup the modem wait status from the sysfs cache
was not removing the previous state properly, because the sysfs path
variable wasn't escaped properly for the sed command.
This patch handles those issues in order to have a proper device
removal handling, by making sure the sysfs path is properly escaped in
the sed command, and by introducing a new hotplug script that runs
when the full USB device is removed.

The procd based init setup uses a custom `pidfile` parameter, but the
used MODEMMANAGER_PID_FILE was not being defined anywhere.
