image_types: Restore pre-btrfs-tools 4.14.1 mkfs.btrfs shrink behavior
Currently the mkfs.btrfs generates large images with a lot of wasted
space. This happens since OE-core updated btrfs-tools from 4.13.3 to
4.15.1 in commit 94b645aa77 ("btrfs-tools: update to 4.15.1") .
Note in mkfs.btrfs(8) manpage section -r says the following:
"
-r|--rootdir <rootdir>
...
Note This option may enlarge the image or file to ensure
it’s big enough to contain the files from rootdir. Since
version 4.14.1 the filesystem size is not minimized. Please
see option --shrink if you need that functionality.
--shrink
Shrink the filesystem to its minimal size, only works with
--rootdir option.
...
Note prior to version 4.14.1, the shrinking was done
automatically.
"
Add the --shrink option to EXTRA_IMAGECMD_btrfs to reinstate the
original behavior and un-waste the space.
