To make eBPF program load time easier to parse from "bpftool prog"
output for machines, change the time format used by the program. The
format now differs for plain and JSON version:
- Plain version uses a string formatted according to ISO 8601.
- JSON uses the number of seconds since the Epoch, wich is less friendly
for humans but even easier to process.
Example output:
# ./bpftool prog
41298: xdp tag a04f5eef06a7f555 dev foo
loaded_at 2018-04-18T17:19:47+0100 uid 0
xlated 16B not jited memlock 4096B
# ./bpftool prog -p

Previously, "Apr 18/17:19" would be used at both places.
