Stricter limits for T3212 (location update period)

libcommon: Default to 30min location update period
libbsc: Limit VTY value for periodic update and disallow the value 0

According to GSM 04.08 Table 10.5.33 "The value 0 is used for infinite
timeout value i.e. periodic updating shall not be used within the cell."

This was the default value until now, but the code that deals with
expiring inactive subscribers in the next commit can't handle that case
so this remains a TODO for now.
