doc: use :command: for subcommands in ceph-bluestore-tool manpage

Older versions of Sphinx, such as the one in CentOS 7, do not render "..
option::" lines correctly if the option contains a hyphen but does not start
with a hyphen. And ceph-bluestore-tool appears to be the only Ceph manpage
affected by this bug.
