[IPVS]: Fix sysctl warnings about missing strategy in schedulers

sysctl table check failed: /net/ipv4/vs/lblc_expiration .3.5.21.19 Missing strategy
[...]
sysctl table check failed: /net/ipv4/vs/lblcr_expiration .3.5.21.20 Missing strategy

Switch these entried over to use CTL_UNNUMBERED as clearly
the sys_syscal portion wasn't working.

This is along the same lines as Christian Borntraeger's patch that fixes
up entries with no stratergy in net/ipv4/ipvs/ip_vs_ctl.c
