Pass kernel release file to check_vintf.

check_vintf now accepts a file that contains the full kernel
release string as the first half of --kernel. Use it.

With this patch, BOARD_KERNEL_VERSION can be a full kernel release
string like 5.4.42-something, or 5.4.42-android12-0-something.

The content of target_files/META/kernel_version.txt also contains the
full kernel release, not just the kernel version.
