[ptxdist] [PATCH v2 2/3] lvm2: add option for libdevmapper-event.so

["Sven Püschel" <s.pueschel@pengutronix.de>]

Add an option for libdevmapper-event.so, as it's not required by
dmsetup. This allows omitting the library, if it's not being used by
any other application on the system.

Signed-off-by: Sven Püschel <s.pueschel@pengutronix.de>
