[Buildroot] [git commit] package/refpolicy: enable systemd support

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=19063d043c11e40cd2fb3f66347fa84ecfc1b1d3
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

This patch enables systemd support in the refpolicy by turning on the
'SYSTEMD' policy build option when systemd is enabled in Buildroot. This
enables conditional rules in SELinux policy modules (by defining
'init_systemd'), to better support systemd.
