[PATCH ha-manager 7/7] test: ha-tester: use colorized diff for unexpected test log outputs

[Daniel Kral <d.kral@proxmox.com>]

Make the diffs for failed integration tests use color, which makes it a
little easier to read on terminals with color support.

diff's --color defaults to --color='auto', which makes sure that diff
does only output the relevant ANSI escape codes for ttys.
