Fix camcontrol timestamp setting and update the man page.

camcontrol timestamp -s would somtimes fail due to stack garbage.  Zero out
the timestamp parameters to fix it.

Fix another nearby bug, and update the man page.

sbin/camcontrol/timestamp.c:
	In set_timestamp(), bzero ts_p prior to creating the timestamp.
	Previously stack garbage could cause some tape drives to reject the
	timestamp.

	In set_timestamp(), check for failures from strptime().

sbin/camcontrol/camcontrol.8:
	Add the time argument to the -T option to camcontrol timestamp -s
	in the long description.

	Change the time/date format used in the camcontrol timestamp
	example to RFC 2822 format.  This fixes a time zone issue with the
	original example by specifying the time zone as -0600.  Otherwise,
	the time zone seems to default to standard time in the current
	locale, which makes the time, when reported back from the drive,
	1 hour off from the intended setting.  This also fixes a duplicate
	day of the week ("Wednesday Wed") in the previous example.
