binfmt_misc: normalize the per-exec invocation flags

Browse source

A static entry fixes its invocation flags at registration. A 'B' entry's
load program picks them per exec. Since load_misc_binary() branches on
which kind of entry matched and then applies the two flag sets side by
side every flag is handled twice and each new one has to be added to
both arms.

Translate the 'B' flags into the entry flags they mirror and let the
dispatch act on a single set of flags. The boolean the two arms
communicated 'P' can be removed.

No functional change.
