Alastair Houghton da4e319d16 [Linux][Backtracing] Don't try to use process_vm_readv(). ...

We used to try to use `process_vm_readv()` if `CAP_SYS_PTRACE` is
enabled.  This avoided using signal handlers to catch crashes when
we try to read through an invalid pointer, but it complicates the
code and it turns out not to work on some Linux kernels where
the `process_vm_readv()` syscall is unavailable.
