ueventd: do not reference init's sehandle
Init exposes a global 'sehandle' that ueventd references as part of
devices.cpp and util.cpp. This is particularly dangerous in
device_init() in which both uevent and init write to this global.
This change creates a separate local copy for devices.cpp and puts
restrictions on where init.h can be included to make sure the global
used by init is not reference by non-init code. Future changes to
init should remove this global.
Test: Boot bullhead
