[SOMA-2553][SOMA-2650] Na sga/server.lua, passar token através do job

- Revertendo alterações no server.lua (não é mais preciso ler nada por
fora do driver, pois o token já vem dentro do objeto job)
- Alterando o driver posix para verificar se o token veio como parâmetro
e, se for o caso, exportar como variável de linha de comando
- Alterado o script request.sh para enviar um token 'fake' para testes
