Export $REBAR_DEPS_DIR and $ERL_LIBS variables
Export two extra environment variables when executing shell commands.
These variables are useful for rebar hooks that rely on Erlang
applications installed as rebar dependencies.
$REBAR_DEPS_DIR contains a fully-qualified name of the directory where
rebar stores dependencies.
$ERL_LIBS is set to $REBAR_DEPS_DIR or to "$REBAR_DEPS_DIR:$ERL_LIBS",
if $ERL_LIBS was defined before.
