Subject: [PATCH] Silence LeakSanitizer by default in mariabackup, so that
 phanthom "leaks" would not hide more interesting information, like invalid
 memory accesses.

some "leaks" are expected
- partly this is due to weird options parsing, that runs twice, and
does not free memory after the first run.
- also we do not mind to exit()  whenever it makes sense, without full
cleanup.
