x86, ds: fix buffer alignment in debug store selftest
The debug store selftest code uses a stack-allocated buffer, which is
not necessarily correctly aligned.
For tests using a buffer to hold a single entry, the buffer that is
passed to ds_request must already be suitably aligned.
Pass a suitably aligned portion of the bigger buffer.
[ Impact: fix hw-branch-tracer self-test failure ]
