[PATCH v2] bitmaps: Update maintainer

[Eric Blake <eblake@redhat.com>]

Dirty bitmaps are important to incremental backups, including exposure
over NBD where I'm already maintainer.  Also, I'm aware that lately I
have been doing as much code/review on bitmaps as John Snow who is
trying to scale back in order to focus elsewhere; and many of the
recent patches have come from Vladimir, who is also interested in
taking on maintainer duties, but would like to start with
co-maintainership.  Therefore, it's time to revamp the ownership of
this category, as agreed between the three of us.
