KVM: arm64: Set ESR_ELx.IL for injected undefined exceptions at EL2

inject_undef64() constructs an ESR with EC=0 (Unknown) but does not set
IL. The architecture mandates IL=1 for EC=0 unconditionally (ARM DDI
0487, ESR_ELx.IL description), so the injected syndrome is one that
conforming hardware cannot produce.

Set ESR_ELx_IL in the constructed syndrome.
