RFR: 8153044: Allow a property to control location of tzdb.dat file

[Roger Riggs]

Hi Sean,

I think I would rename the property to "jdk.time.zone.tzdbfile" to 
reinforce it is captive to the zone implementation.

Though the original code builds the path with string concatenation, I 
think it would be better
to use java.nio.Paths.get() to build it.
   i.e. Paths.get(getProperty("java.home"), "lib", "tzdb.dat").

Also, for the property access in the case of a security manager,
use  sun.security.actions.GetPropertyAction.privilegedGetProperty.

Perhaps rename 'pathToRules' to 'pathToTzdb'

Thanks, Roger
