Don't prepend blktrace destination dir if we didn't run blktrace

When user specifies trace files directly via -t option, it doesn't make
sense to prepend blktrace destination directory to them (it is
especially confusing if you specify absolute path names with -t option
and this logic breaks the path names). So avoid that.
