awgtpman: removal of old build flags that broak setting testpoints

We'd dropped an old build flag that was used to determine the element element size for test point numbers.

The testpoint size reverted from 4 bytes to t2, but only in the RPC definition. As a result, only the first value in an RPC array of testpoints was in the correct position. Only one testpoint could be specified correctly per test.

This change drops the flag check and forces the RPC element size to 4 bytes.

I've checked the rest of the code to make sure this was the only remaining use of the build flags.

Closes #372 (closed).
