Convert 'sane_execvp()' to 'sane_execvpe()' which optionally takes a
pointer to an array of 'char *' which should be used as the environment
for the process being exec'd. If no environment is provided (by passing
NULL instead) then the already existing environment, as stored in
'environ', will be used.
