chore(appup): make update_appup.escript output only differences for external dependencies
Currently, the update_appup.escript outputs as an error the full appup
file for external dependencies, even if all the changes are already
contained in the depency. Here, we make it only output the missing
actions to be inserted, to aid in seeing what are the differences.

feat(sys_mon): Add proc_lib:initial_call/1 and current_stacktrace (4.3)
(Same as #6289 )
This adds the information from `proc_lib:initial_call/1` and the
current stacktrace from the process info to `emqx_sys_mon:procinfo/1`
to aid in debugging some warnings with no context such as the
following:
```

chore(appup): minor fixes to update_appup.escript
- Fixes clause error on `create_stub/1`.
- Small optimization: do not download the same file multiple times
with `wget`.
- Fix: remove old file extension (`.app.src`) and preserve dirname
when creating stubs for apps.
prior to this change, the OTP_VSN varaible was taken from
the docker host's OTP version which may differ from the
desired OTP version for the docker builder image.
