tests/tcg/aarch64: force qarma5 for pauth-3 test

The pauth-3 test explicitly tests that a computation of the
pointer-authentication produces the expected result.  This means that
it must be run with the QARMA5 algorithm.

Explicitly set the pauth algorithm when running this test, so that it
doesn't break when we change the default algorithm the 'max' CPU
uses.
