Updated py-borgbackup to 1.0.2.

Version 1.0.2
-------------

Bug fixes:

- fix malfunction and potential corruption on (nowadays rather rare) big-endian
  architectures or bi-endian archs in (rare) BE mode. #886, #889

  cache resync / index merge was malfunctioning due to this, potentially
  leading to data loss. borg info had cosmetic issues (displayed wrong values).

  note: all (widespread) little-endian archs (like x86/x64) or bi-endian archs
  in (widespread) LE mode (like ARMEL, MIPSEL, ...) were NOT affected.
- add overflow and range checks for 1st (special) uint32 of the hashindex
  values, switch from int32 to uint32.
- fix so that refcount will never overflow, but just stick to max. value after
  a overflow would have occured.
- borg delete: fix --cache-only for broken caches, #874

  Makes --cache-only idempotent: it won't fail if the cache is already deleted.
- fixed borg create --one-file-system erroneously traversing into other
  filesystems (if starting fs device number was 0), #873
- workround a bug in Linux fadvise FADV_DONTNEED, #907

Other changes:

- better test coverage for hashindex, incl. overflow testing, checking correct
  computations so endianness issues would be discovered.
- reproducible doc for ProgressIndicator*,  make the build reproducible.
- use latest llfuse for vagrant machines
- docs:

  - use /path/to/repo in examples, fixes #901
  - fix confusing usage of "repo" as archive name (use "arch")
