  1. actions/image-partition: check partition name length in verify stage 

    The partition name (label) can be up to 11 characters long for vfat
and 16 characters long for ext3/4.

When partition name length is longer than 11 characters for vfat,
it fails with below message,
==== image-partition ====
cmdline: [mkfs.vfat -F32 -n efi456789012 /dev/vda1]
Formatting partition 1 | mkfs.vfat: Label can be no longer than 11 characters
Formatting partition 1 | mkfs.fat 4.2 (2021-01-31)
Action `image-partition` failed at stage Run, error: exit status 1

When partition name length is longer than 16 characters for ext2/3/4,
it shows the below warning message,
cmdline: [mkfs.ext4 -L root567890123456789 /dev/vda2]
Formatting partition 2 | Warning: label too long; will be truncated to 'root567890123456'

In case the partition name is longer than 11 for vfat, name is truncated
to 11 characters and a warning message is reported. In case of ext3/4,
it is truncated to 16 characters.
