  ipfix: Bug fix for not sending template packets on 32-bit OS

'last_template_set_time' in truct dpif_ipfix_exporter is declared
as time_t and time_t is long int type. If we initialize
'last_template_set_time' as TIME_MIN, whose value is -2147483648
on 32-bit OS and -2^63 on 64-bit OS. There will be a problem on
32-bit OS when comparing 'last_template_set_time' with a unisgned int
type variable, because type casting will happen and negative value
could be a large positive number. Fix this problem by simply initialize
'last_template_set_time' as 0.
