bash-completion: Add fallback for symlinks/images

For commands which support operating on files (i.e. disk images), it is
desirable for bash-completion to complete matching file names.  It is
also desirable to complete on block device symlinks (e.g. under
/dev/disk).  To complete common use cases, often on canonical device
names, continue to try completion using canonical device names, then
fall back to matching any file incrementally as Bash does by default.[1]
