- Add 'compile_multilib: "both"' to FsVerityTestApp. Without this,
installation with the 32-bit ABI on a 64-bit system fails with
error INSTALL_FAILED_NO_MATCHING_ABIS.
- Switch from SuiteApkInstaller to installPackage() in a @Before method.
Without this, 'atest --all-abi FsVerityTest' does not work because the
APK gets installed with the 64-bit ABI for the 64-bit test and then
doesn't get reinstalled with the 32-bit ABI when the 32-bit test runs,
causing the 32-bit test to be unable to find libfsveritytestapp_jni.so
