[PATCH 1/2] ref-filter: mark a file-local symbol as static

Commit fcfba37337 ('ref-filter: make "--contains <id>" less chatty if
<id> is invalid', 2018-02-23) added the add_str_to_commit_list()
function, which causes sparse to issue a "... not declared. Should it
be static?" warning for that symbol.

In order to suppress the warning, mark that function as static.
