strata: skip two more QEMU-only aarch64 tests

With the search race skipped, the aarch64 main suite ran to the end:
2339 passed, 2 failed. a_missing_working_directory_... expects spawn to
fail on a missing cwd, which posix_spawn cannot report under QEMU
user-mode. in_place_retirement_... identifies its process by
/proc/<pid>/exe, which names /usr/bin/qemu-aarch64 there, not sleep.
