perf scripts python: exported-sql-viewer.py: Fix zero id in call tree 'Find' result
Using ctrl-F ('Find') would not find 'unknown' because it matches id
zero. Fix by excluding id zero from selection.
Example:
$ perf record -e intel_pt//u uname
Linux
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.034 MB perf.data ]
$ perf script --itrace=bep -s ~/libexec/perf-core/scripts/python/export-to-sqlite.py perf.data.db branches calls

2020-06-26 15:32:15.549716 Done
$ python3 ~/libexec/perf-core/scripts/python/exported-sql-viewer.py perf.data.db
Select: Reports -> Call Tree
Press: Ctrl-F
Enter: unknown
Press: Enter
Before: displays 'unknown' not found
After: tree is expanded to line showing 'unknown'
