[PATCH] only document --faked-system-time for gpg 2.1 and later

[Daniel Kahn Gillmor]

faked-system-time is not present at all in the codebase for 1.4; it is
present only for gpgsm and gpg-agent (not gpg itself) in 2.0; it
appears in gpg for 2.1.  This patch adjusts the gpg documentation
appropriately.

(The other way to resolve the problem would be to backport the
faked-system-time call to earlier branches of gpg)

 This option is only useful for testing; it sets the system time back or
 forth to @var{epoch} which is the number of seconds elapsed since the year
 1970.  Alternatively @var{epoch} may be given as a full ISO time string
 (e.g. "20070924T154812").
