fix(release): pin capability bounding set in gost.service

Browse Source 
CapabilityBoundingSet= was dropped when CAP_NET_ADMIN was added for TUN,
which leaves the bounding set unrestricted. Pin it to the capabilities the
unit actually needs. Restore ~@privileged as well: TUN uses ioctl(TUNSETIFF)
and netlink, neither of which is in that group.
