imx-base: Improve sstate signature handling for BSP packages
There are BSP packages which can have some dependencies removed from
the sstate signature; this is beneficial as it reduces a lot the build
time and increases the binaries reuse.
Following changes are done:
- Mark kernel-module-imx-gpu-viv and safe for imx-gpu-viv
- Mark imx-vpu as safe for libimxvpuapi
- Mark imx-vpu as safe for imx-vpuwrap
- Mark imx-vpu as safe for imx-codec
- Mark imx-vpu as safe for imx-test
