trace: Improve the trace test number recognition

Browse Source 
The awk tool can be confused by return character (ASCII 13) in its input
since it thinks there is a separate field. These can appear if the terminal
is in raw mode, perhaps due to a previous U-Boot crash with sandbox. This
is very confusing. Remove these so that the trace test passes.
