fs/xattr: bpf: Introduce security.bpf. xattr name prefix
Introduct new xattr name prefix security.bpf., and enable reading these
xattrs from bpf kfuncs bpf_get_[file|dentry]_xattr().
As we are on it, correct the comments for return value of
bpf_get_[file|dentry]_xattr(), i.e. return length the xattr value on
success.
