Bug#906873: linux-base: linux-version returns invalid information if gpg kernel signatures are present

Package: linux-base
Version: 4.5
Severity: normal

Dear Maintainer,

I am using grub with `check_signatures` set to `enforce`. This requires gpg-
style detached signatures in the boot directory. `linux-version` incorrectly
lists these signatures as kernel versions.

Recently, initramfs-tools seems to have switched to using linux-version to get
the most recent kernel version and so now `update-initramfs` doesn't work
unless I remove these files first.
