Subject: [PATCH] fix detection of kernel modules on 64-bit image
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The lib modules folder looks like `/lib/modules/6.1.21-v8+/build`, which
means that the previous regex doesn't capture anything after the `-` and
therefore it fails to detect the kernel version.
The regex now aligns with the other detection method and this works fine
on my machine™
