packbeam --external requires full path

[pguyot]

Surprisingly, it seems that

rebar3 atomvm packbeam -e estdlib/estdlib.avm -e eavmlib/eavmlib.avm

doesn't work and fails with enoent, while:

rebar3 atomvm packbeam -e `pwd`/estdlib/estdlib.avm -e `pwd`/eavmlib/eavmlib.avm

does work.

I guess the current working directory is not where rebar3 is invoked from. It should at least be mentioned in documentation.

Indeed. It is only vaguely implied in the example of packing an external file… But not stated explicitly. I will change the help to say this should be the full path to the avm file, and make it clear in the documentation as well.

Please take a look at PR #36, it enables using relative paths as well for external AVMs.
