buildhistory.bbclass: Improve robustness in image file listing

The filenames sometimes may have strange names. With the 'awk' script
it handled a limited number of spaces in the filename and a package
installing a file named "test file with spaces" would have its name
truncated.

This patch uses the find's printf formating to simplify the code and
properly handle this case. From a testing image, the only diff produced
is:

,----[ files-in-image.txt diff ]
| --rwxr-xr-x root       root                0 ./usr/bin/test\ file\ with\
| +-rwxr-xr-x root       root                0 ./usr/bin/test file with spaces
`----

The options used are available since findutils 4.2.5, released in 19
Nov 2004, making it available in all supported host distributions.
