c1b7a9cd64 wic: don't forcibly pass -T default
This reverts part of oe-core eecbe62555, which was a previous attempt
to solve the Y2038 problem.  This is now solved centrally in e2fsprogs,
so doesn't need to be dealt with in wic.

We don't revert the commit entirely, to retain the warning if a
filesystem has small inodes.

a334cbb12d wic: Warn if an ext filesystem affected by the Y2038 problem is used
We are getting closer and closer to the year 2038 where the 32 bit
time_t overflow will happen. While products (= embedded systems) with an
expected life time of 15 years are still save the situation may change
if your system has to survive the next 20 years.

ext2 and ext3 filesystems are always affected by the time overflow, so
let's warn the user if these filesystems are still being used.

If ext4 is affected depends on the inode size chosen during filesystem
creation. At least 256 bytes are necessary to be safe. As ext4 is
used very often (and partitions may be created small first and extended
later) this might be an issue for many users.

Some filesystems created during CI runs were already affected by the Y2038
problem. By using `--mkfs-extraopts "-T default"` we tell mke2fs not to
auto-detect the usage type based on the filesystem size. mke2fs will use
the default values for tuning parameters instead. The inode size is one
of these parameters.

03d5daf1ae wic: Switch to using --use-uuid by default
The most portable way to specifiy a root device in a disk image that we
create is to use PARTUUID rather than /dev/sda2.  As background, both
GPT and MBR tables provide valid UUID values for each partition and the
Linux Kernel contains the logic to parse this value.  With this change
we can now boot the default disk images when used as any valid block
device that the included kernel uses.  This for example means that
VirtualBox can be used to run vmdk without changes as it uses IDE for
the virtual disk controller.
