[PATCH] dir.c: mark a file local function as static

Commit b74884b86 ("untracked cache: make a wrapper around
{open,read,close}dir()", 27-10-2014) added the read_cached_dir()
function as an external symbol.

Noticed by sparse. ("'read_cached_dir' was not declared. Should it
be static?").

Hi Duy,

If you need to re-roll your 'nd/untracked-cache' branch, could you
please squash this into the relevant patch.

Thanks!

[If this function is destined to be used from external call sites
in future patches, then adding an extern declaration to "dir.h"
would be an alternative, of course. ;-) ]

ATB,
Ramsay Jones
