Partially revert "net: socket: implement 64-bit timestamps"

The introduction of SIOCGSTAMP{,NS}_OLD and move of SICOGSTAMP{,NS} to
a different header has caused build failures for various user-space
programs including qemu and suricata.  It also causes a test failure
for glibc.

For now, remove the _OLD suffix on the old ioctl numbers and require
programs using 64-bit timestamps to explicitly use SIOCGSTAMP{,NS}_NEW.
