swift/sysctl: do not disable net.ipv4.tcp_timestamps

Browse Source 
Turn timestamps off to reduce performance spikes related to timestamp
generation. The sysctl command controls the values of TCP related
entries, setting the timestamps kernel parameter found at
/proc/sys/net/ipv4/tcp_timestamps.

It should be enabled in order to make Swift & Ceph working correctly.
