From: srinuvasan <srinuvasan.a@siemens.com>

In some use-cases we need to install custom packages in sbuildchroot and
this can be referred later time during image generation part, hence we
additionally added the provision to install the custom packages in
sbuild flavor.

Introduced SBUILD_CHROOT_INSTALL variable, here you can define the
custom packages that you need to install in sbuild flavor.

   Hmm, Let me try with DEPENDS , but you added the dependencies via 
DEPENDS in base sbuild-chroot [target/host], if i add all my dependencies 
here it may increases the size of bare-metal sbuild-chroot , i will check 
this DEPENDS for sbuild flavor too.

This is specific to the case above:

sbuild-chroot-host -> keyutils (built non-cross) -> sbuild-chroot-target

This is specific to the case above: 

sbuild-chroot-host -> keyutils (built non-cross) -> sbuild-chroot-target

That provision comes with

- I suspect I should have explicitly names this dependency of my riscv 
series.
