When specifying an OS version it builds `2.75*` rather than just `2.75`

[maggie44]

When specifying an OS version to build it seems to build for all kernels starting with the os-version provided rather than just that specific build. For example:

--os-version "2.99.27"

builds 2.99.27 and:

...
2.99.27+rev5
2.99.27+rev5_from_src
...

Is this expected? I only need the one specified and it slows down the build time. Since dropping dev and prod versions at Balena in favour of 1 configurable image this I occurring more often as there isn't a more specific version passed.
