journal-file: handle SIGBUS on offlining thread

offlining thread so that it uses the same handler as the main thread.

undefined in Linux. The tested implementations were observed to cause
the default handler to run, taking down the whole journald process.

Change Razer Abyssus DPI in 70-mouse.hwdb (#12029)

As discussed in https://gitlab.freedesktop.org/libinput/libinput/issues/198#note_100642 the DPI for the Razer Abyssus mouse is not 3500 by default, but around 1600-1700 when measured with the mouse-dpi-tool.

So I have done some measurements now and always got a value of about 21000 device units on a distance of 12.5 inch. This would result in a calculated resolution of about 1680 DPI. Since such an odd number does not occur in the hwdb file I decided to round to 1600 DPI.
