[IPVS]: Fix sysctl warnings about missing strategy

Running the latest git code I get the following messages during boot:
sysctl table check failed: /net/ipv4/vs/drop_entry .3.5.21.4 Missing strategy
[...]		  
sysctl table check failed: /net/ipv4/vs/drop_packet .3.5.21.5 Missing strategy
[...]
sysctl table check failed: /net/ipv4/vs/secure_tcp .3.5.21.6 Missing strategy
[...]
sysctl table check failed: /net/ipv4/vs/sync_threshold .3.5.21.24 Missing strategy

I removed the binary sysctl handler for those messages and also removed
the definitions in ip_vs.h. The alternative would be to implement a 
proper strategy handler, but syscall sysctl is deprecated.

There are other sysctl definitions that are commented out or work with 
the default sysctl_data strategy. I did not touch these.
