[sheepdog] [PATCH 2/2] sheep: add static declaration to internal function

[Saeki Masaki]

Future, we want to make an extension of the backend store using --store option.
For backend store expansion, internal function must be concealed,
so add a static declaration.

in order to adapt this modify, change the interface of md_exist().
