binfmt_misc: document registering an entry disabled

Browse source

Describe the 'D' flag and what it changes about a registration:

- that the entry has to be enabled before it dispatches anything
- and that the flag is not read back

Scope the bpf section's "carries no flags" rule to invocation flags now
that 'D' composes with 'B'.
