[PATCH] sample/auto.smb: Use AUTOFS_ prevised environment variables

As the default value for 'force_standard_program_map_env' from
autofs.conf(5) is 'no', for a program map that uses the UID and GID
standard environment variables they are prefixed with "AUTOFS_".

To match the behaviour under default conditions of
'force_standard_program_map_env' use AUTOFS_UID and AUTOFS_GID in the
sample code for the auto.smb program map.
