Chore build update rebar3 version (#4303)

* chore(Makefile): Delete unnecessary exports for deps-get

* chore(rebar3): upgrade to rebar3 version 3.14.3-emqx-5

This rebar3 version does not copy .git directory.
Before this, if a plugin repo clone is placed in lib-extra,
rebar2 ct or eunit commnad may fail at source code copy step.
