1. aot: Enable aot built binaries to run …

   Fixes a couple issues with aot built binaries that was preventing
   runtime from functioning.
   
   Namely, we were looking in the wrong place in the ELF file for the
   custom .btaot section that we added. We were also not serializing the
   map of BpfMaps contained in BpfBytecode, which is necessary for runtime.
   Finally, I fixed maps not being printed out correctly when bpftrace exits.

2. aot: Allow running aot binaries directly without calling runtime shim …

   Currently, even though we make a copy of the runtime shim and then
   embed the necessary metadata + bytecode into the binary, you still need
   to pass that binary as an argument to the runtime shim in order to run
   it (i.e. you need to do 'bpftrace-aotrt <file_name>'). Since the binary
   can fully function on its own, we don't need to do this anymore.
   
   This commit makes the executable just look inside itself for the
   metadata and bytecode, skipping the need to call bpftrace-aotrt. (i.e.
   you can now run the binary with just ./<file_name>.)
