From: Roberto Sassu <roberto.sassu@huawei.com>
In preparation for the patch that introduces the bpf_lookup_user_key() eBPF kfunc, move KEY_LOOKUP_ definitions to include/linux/key.h, to be able to validate the kfunc parameters.
Also, define the new constant KEY_LOOKUP_FLAGS_ALL, to facilitate checking whether a variable contains only defined flags.
