[PATCH v2] selftests/sgx: add test_encl.elf to TEST_GEN_FILES

[Jarkko Sakkinen <jarkko@kernel.org>]

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.

[*] https://docs.kernel.org/dev-tools/kselftest.html

Cc: stable@vger.kernel.org
Fixes: 2adcba79e69d ("selftests/x86: Add a selftest for SGX")
Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org>

v2:
Use TEST_GEN_FILES in the "all" target, instead of duplicating the path for
test_encl.elf.
