Avoid trunc error in smarsa_BirthSpacings in bigcrushJulia

[GregPlowman]

Issue #28

Fix for bigcrushJulia battery test.
Use alternative parameters for smarsa_BirthdaySpacings to avoid error when passing 2^31 to Clong argument on Windows, where Clong is defined as Int32.

Copied alternative parameters from TestU01 c code (testu01/bbattery.c)
