When ptrace is completely unavailable, rather than report false positives, LSAN should print appropriate warning.

Make lsan complain loudly when running under ptrace
1f98745 
Summary:
LeakSanitizer does not work with ptrace but currently it
will print warnings (only under verbosity=1) and then proceed
to print tons of false reports.
This patch makes lsan fail hard under ptrace with a verbose message.
