[libnftnl PATCH 2/2] set_elem: Include key_end data reg in print output

[Phil Sutter <phil@xxxxxx>]

Elements of concatenated range sets hold the upper boundary in an extra
data_reg, print it using dash as a somewhat intuitive separator.

Fixes: 04cc28d8d6923 ("set_elem: Introduce support for NFTNL_SET_ELEM_KEY_END")
