Precedence: bulk

With some of the stricter type checking in KUnit's EXPECT macros
removed, several casts in policy_unpack_test are no longer required.

Remove the unnecessary casts, making the conditions clearer.

This is a rebase and resend of [1], which had been accepted into the
AppArmor tree, but eventually conflicted with [2]. Let's push it via the
KUnit tree to avoid any further conflicts, as discussed in [3].

Cheers,
