selftests/sgx: Specify freestanding environment for enclave compilation
Use -ffreestanding to assert the enclave compilation targets a
freestanding environment (i.e., without "main" or standard libraries).
This fixes clang reporting "undefined reference to `memset'" after
erroneously optimizing away the provided memset/memcpy implementations.
Still need to instruct the linker from using standard system startup
functions, but drop -nostartfiles as it is implied by -nostdlib.
