Enable /dev/sgx_vepc access for the group 'sgx'

Browse source 
Enable /dev/sgx_vepc access for the group 'sgx', which allows KVM-backed VMs
to host Intel Software Guard eXtension (SGX) enclaves. The upcoming QEMU
6.2 uses /dev/sgx_vepc to reserve portions of Enclave Page Cache (EPC) for
VMs. EPC is the reserved physical memory used for hosting enclaves.
