x86/tools: insn_decoder_test.c: Emit standard build success messages

The standard 'success' output of insn_decoder_test spams build logs with:

  arch/x86/tools/insn_decoder_test: success: Decoded and checked 8258521 instructions

Prefix the message with the standard '  ' (two spaces) used by kbuild to denote
regular build messages, making it easier for tools to filter out
warnings and errors.
