DO NOT MERGE: debuggerd: verify that traced threads belong to the right process.
Fix two races in debuggerd's PTRACE_ATTACH logic:
1. The target thread in a crash dump request could exit between the
/proc/<pid>/task/<tid> check and the PTRACE_ATTACH.
2. Sibling threads could exit between listing /proc/<pid>/task and the
PTRACE_ATTACH.
