sanity.bbclass: add extra information when SSTATE_CACHE unusable

If the user does not have write permissions to SSTATE_CACHE, detected by
the check_create_long_filename() test failing with a "Permission denied"
value in strerror, then suggest they might want to use the location as
an entry in SSTATE_MIRRORS.
