[PATCH] selftests/sgx: add test_encl.elf to TEST_GEN_FILES

[PATCH] selftests/sgx: add test_encl.elf to TEST_GEN_FILES

[Jarkko Sakkinen]

TEST_GEN_FILES contains files that are generated during compilation and are
required to be included together with the test binaries, e.g. when
performing:

make -C tools/testing/selftests install INSTALL_PATH=/some/other/path [*]

Add test_encl.elf to TEST_GEN_FILES because otherwise the installed test
binary will fail to run.

I found this while trying to create an image with BuldRoot containing
the self-tests:

https://github.com/jarkkojs/buildroot-sgx

On SGX capable machine can be built and run in QEMU as

make sgx_x86_64_defconfig && make && output/image/run.sh
