forward SSTATE_MIRRORS environment variable

In case cache artifacts are not found in SSTATE_DIR, the sstate logic continues to search in the SSTATE_MIRRORS. By that, we also need to automatically forward this variable. Previously, users had to manually add this variable to the env section of a kas file. Signed-off-by: Felix Moessbauer <[email protected]> Signed-off-by: Jan Kiszka <[email protected]>
