selftests/sgx: Fix corrupted cpuid macro invocation
The SGX selftest fails to build on tip/x86/sgx: main.c: In function ‘get_total_epc_mem’: main.c:296:17: error: implicit declaration of function ‘__cpuid’ [-Werror=implicit-function-declaration] 296 | __cpuid(&eax, &ebx, &ecx, &edx); | ^~~~~~~ Include cpuid.h and use __cpuid_count() macro in order to fix the compilation issue.
