tests: Generate testdata for 2nd arch.

We currently only copy the testdata to
$(TARGET_OUT_DATA_NATIVE_TESTS)/recovery, which fails the tests
generated for 2nd arch (TARGET_2ND_ARCH). For example, on angler
/data/nativetest/recovery_component_test/recovery_component_test fails
due to missing testdata.

Bug: 32123241
Test: Both of /data/nativetest/recovery... and /data/nativetest64/recovery...
work on angler.
