    Add NetBSD LSan support

    Summary:
    Combine few relatively small changes into one:

     - implement internal_ptrace() and internal_clone() for NetBSD
     - add support for stoptheworld based on the ptrace(2) API
     - define COMPILER_RT_HAS_LSAN for NetBSD
     - enable tests for NetBSD/amd64

    Inspired by the original implementation by Christos Zoulas in netbsd/src for GCC.

    The implementation is in theory CPU independent through well defined macros
    across all NetBSD ports, however only the x86_64 version was tested.
