target/i386: fix TF/RF handling for HLT

HLT uses DISAS_NORETURN because the corresponding helper calls
cpu_loop_exit().  However, while gen_eob() clears HF_RF_MASK and
synthesizes a #DB exception if single-step is active, none of this is
done by HLT.  Note that the single-step trap is generated after the halt
is finished.
