perf branch: Fix interpretation of branch records

Commit 93315e4 ("perf/core: Add speculation info to branch
entries") added a new field in between type and new_type. Perf has its
own copy of this struct so update it to match the kernel side.

This doesn't currently cause any issues because new_type is only used by
the Arm BRBE driver which isn't merged yet.

Committer notes:

Is this really an ABI? How are we supposed to deal with old perf.data
files with new tools and vice versa? :-\
