Fix #139: System timezone changes does not 'take' in Finit

The tzset() function sets the global variables 'daylight', 'timezone' and 'tzname'
according to the value of the TZ environment variable, or to the value of the
_CS_TIMEZONE configuration string if TZ isn't set, or to UTC0 if neither is set.
