Use proper program id in program tests

[buffalojoec]

Problem

In the first BPF implementation of the program, we had to temporarily use an
arbitrary program ID in order to successfully test the program as a BPF
program.

Now that 2.0 is released, we can use add_upgradeable_program_to_genesis
to add a Core BPF program to the Bank and prevent it from being overwritten
by its original builtin counterpart.

Summary of Changes

Update the tests to use this new method, and the proper ID for the program!
