[PATCH v2 6/9] docker: Drop tracing for arm64

[Simon Glass]

This doesn't build on arm64 at present, so drop it for now. This can be
revisited if we wish to support arm64 for the sandbox trace-test.

The error is:
   /usr/bin/ld: /usr/local/lib64/libtracefs.so: undefined reference to
      `trace_seq_vprintf'
