app-backup/backuppc: Prune unnecessary formatting changes from patches

Patch set included 22kb of cosmetic changes, some of which were not really
cosmetic at all, while being pretended as being cosmetic.

For instance, changing the default umask from 027 to 27 ignores the fact
that a '0' prefix implies octal, so removing the '0' turned the umask from
027 to 033 ....

That is, changes:

  - u=rwx,g=rx,o=rx
  + u=rwx,g=r,o=r

However, some of the changes had real semantic differences that could
affect picky enough code, so I've preserved some of them, while culling
those that were completely unnesscary.

If this revert-of-patch introduces problems for you, please file a bug
so we can triage the real problems under an umbrella more well defined than
"formatting"
