[Buildroot] [PATCH 2/2] package/boost: threads needs date-time

[Fabrice Fontaine]

Fix the following build failure with gcc >= 7 raised since commit
4e267a7d3d5d350710a81ada188a1629348e4b4a because cmake assumes that
boost threads needs boost date-time:

-- Found Boost: /home/buildroot/autobuild/instance-3/output-1/host/sh4-buildroot-linux-uclibc/sysroot/usr/include (found version "1.77.0") found components: thread chrono atomic missing components: date_time

Fixes:
