tracing/filters: operand can be negative

This should be a bug:

 # cat format
 name: foo_bar
 ID: 71
 format:
 ...
         field:int bar;  offset:24;      size:4;
 # echo 'bar < 0' > filter
 # echo 'bar < -1' > filter
 bash: echo: write error: Invalid argument

[ Impact: fix to allow negative operand in filer expr ]
