Explict call to the terralib:finalize()

[avancinirodrigo]

TerraME must call finalize() expecitly. Investigate how make this transparently for user.

[pedro-andrade-inpe]

Add to terrame.lua _Gtme.execute(arguments) in the end of this function.

@pedro-andrade-inpe, this solution works in normal execution, but in -testnot.

[pedro-andrade-inpe]

-test calls os.exit() explicitly in the end. Remove terralib also in terrame.lua, in the end of

elseif arg == "-test" then

just before os.exit().
