[PATCH] libselinux: Ignore missing directories when -i is used

[Vit Mojzis <vmojzis@xxxxxxxxxx>]

Currently "-i" only ignores a file whose parent directory exists. Start also
ignoring paths with missing components.

Fixes:
  # restorecon -i -v -R /var/log/missingdir/missingfile; echo $?
  255
  restorecon: SELinux: Could not get canonical path for /var/log/missingdir/missingfile restorecon: No such file or directory.
