Tomáš Hozza d7e960f0c1 Internal: delete unused common.VersionLessThan()
The function is a leftover from the image definitions split and it is
not used. Moreover, the `images` copy of it is being reimplemented by
[1]. It is better to remove this copy to prevent any unintended use of
it or confusion.
