cmd/compile/internal/ssa: restrict architectures for TestDebugLines_74576

CL 687815 recently added TestDebugLines_74576.

The pre-existing debug_lines_test.go file generally restricts the
tested architectures and contains multiple warnings that the
testing approach is useful but fragile, such as:

  "These files must all be short because this is super-fragile."

Despite that, initially I wanted to see what happened on the
different architectures on the trybots in case it might show something
surprising, and I let TestDebugLines_74576 run on all architectures.

That seemed to initially work, but the test is now failing on a
linux/risc64 builder (#74669), so it is likely more prudent to be
more conservative and restrict the platforms like many of the
other pre-existing tests, which is what this CL now does.

Fixes #74669
