I am not sure about the naming here ... it is _very_ close to
(and thus appears to be in the same namespace as)
TEST_TIMEOUT_DEFAULT from the included kselftest_harness.h.

This is surely a nitpick but how about SGX_TEST_TIMEOUT_DEFAULT?

There is an extra empty line here ... but it looks like intended code
organization?

Apart from the naming comment this addition looks good.

This is a valuable addition to the SGX tests.
