 untar: do not exit with error when created directory already exists.

 The problem exists for both RTEMS untar implementations and their
 variants: Untar_FromMemory(), Untar_FromFile() and rtems_tarfs_load().

 If filesystem object already exists at extracted directory path
 then if it is directory, creation is ignored. Attempt
 to delete/unlink object and make directory is tried for other cases.

 This simple approach problem reported in ticket fixes #2413.
 Behavior follows GNU tar and BSD tar practice for directories
 but much more work is required to achieve full semantics
 of the full featured tar implementation still.
