partman/resize: add a margin to the minimal size for partition shrinking

The current estimation of the minimal size of a filesystem is used as-is
without any margin. However these are only estimations and filesystems
shrunk to their minimum are not usable anymore. This is especially the
case for ext4 since the estimation does not take into account the
numerous filesystem features.

For ext4 we could improve the estimation too but this is a difficult
task with shell scripting and probably not worth considering the issue
has probably existed for a long time and no user seems to have
complained so far (maybe they worked around the issue by not trying to
shrink as much as possible).

Therefore, add the same margin as in subiquity: max(minsize*0.25, 2GiB).
