net: add sock_set_reuseaddr
Add a helper to directly set the SO_REUSEADDR sockopt from kernel space
without going through a fake uaccess.
For this the iscsi target now has to formally depend on inet to avoid
a mostly theoretical compile failure. For actual operation it already
did depend on having ipv4 or ipv6 support.
