run-postinsts: Print message before running deferred postinst scripts 

Opkg can defer running postinst scripts to first boot, which can take
a while on some systems. The output of `opkg configure` (or whatever pm
is used) is redirected to a file when logging is enabled
(I.e. $POSTINST_LOGGING == 1), making the machine appear hung during
this process. This change simply prints a wait message on the console
to inform the user of this potentially long and silent operation so
that they do not mistakenly reboot their machine.

Why not simply `tee` the output instead?
Tee might be provided by BusyBox in some distros, which may need to run
update-alternatives in the very postinst scripts being executed by this
process. It's therefore not safe to assume Tee (or any other packaged
util) is available until the configure process finishes.
