tail: use consistent diagnostics with and without inotify
* src/tail.c: With inotify, when a file is initially absent, we fstat(-1) for that file spec, thus recording an errnum of EBADF, which caused the "has become accessible" diagnostic to be issued, when the file first appears. Instead we avoid the fstat(-1) and thus emit the more natural and consistent "has appeared" diagnostic. * tests/tail-2/retry.sh: Use the new diagnostic which also causes this test to pass on systems without inotify.
