[PATCH 2/2] qemu-iotests: fix image-fleecing pylint errors

[Emanuele Giuseppe Esposito <eesposit@redhat.com>]

The problem here is that some variables are formatted with
unnecessary spaces to make it prettier and easier to read.

However, pylint complains about those additional spaces.
A solution is to transform them as string with arbitrary spaces,
and then convert it back into a tuple.

Removing the spaces makes it a little bit ugly, and directly
using the string forces us to change the test reference output
accordingly, which will 1) contain ugly weird formatted strings,
2) is not portable if somebody changes the formatting in the test
string.
