[rdiff-backup-users] doesn't handle user "nobody"

[Chris Dumont]

Hi,

Some files in a filesystem to be backed up were owned by the 32-bit version of "nobody" (not that I wanted them to be but that's another story). Numerically this is -2 or  4294967294. This made rdiff-backup 1.2.5  crash (see below). Changing the owner to root works around the problem.
