udev: override new udev default timeout of 30s to original 3min

New versions of udev changed the default event timeout to 30s
from original 3min. This causes problems with LVM processes that
starve because of the IO load caused by some LVM actions (e.g.
mirror/raid synchronization).

Reinstate the 3min udev timeout for now until we optimize this
in a way that even the 30s timeout is sufficient.
