x86/insn: Fix CTEST instruction decoding
insn_decoder_test found a problem with decoding APX CTEST instructions:
Found an x86 instruction decoder bug, please report this.
ffffffff810021df 62 54 94 05 85 ff ctestneq
objdump says 6 bytes, but insn_get_length() says 5
It happens because x86-opcode-map.txt doesn't specify arguments for the
instruction and the decoder doesn't expect to see ModRM byte.
Fixes: 690ca3a3067f ("x86/insn: Add support for APX EVEX instructions to the opcode map")
