tempname: fix int precision warnings

The printf precision takes an integer, not a size_t.  Otherwise we get:

libc/misc/internals/tempname.c: In function '___path_search':
libc/misc/internals/tempname.c:116: warning:
	field precision should have type 'int', but argument 3 has type 'size_t'
	field precision should have type 'int', but argument 5 has type 'size_t'
