fix crash on unaccessible input files

Fix i2n bug #6440: race condition between access(3) and open(2).

This flaw exists in both the full and diff backup code. Deltatar
must not assume that the verdict returned by access() will hold
true later. Emit a warning if we receive ENOENT on later calls to
open(), but continue regardless.
