setenv(): Delete 0-length environment variables
Previously setenv() would only delete an environment variable if it
was passed a NULL string pointer as a value. It should also delete an
environment variable when it encounters a valid string pointer of
0-length.
This change/fix is generally useful and is necessary for the upcoming
"editenv" command.
