pktgen: adjust flag NO_TIMESTAMP to be more pktgen compliant

Allow flag NO_TIMESTAMP to turn timestamping on again, like other flags,
with a negation of the flag like !NO_TIMESTAMP.

Also document the option flag NO_TIMESTAMP.

Fixes: afb84b62 ("pktgen: add flag NO_TIMESTAMP to disable timestamping")
