buildman: Add a --boards option to specify particular boards to build

At present 'buildman sandbox' will build all 5 boards for the sandbox
architecture rather than the single board 'sandbox'. The only current way
to exclude sandbox_spl, sandbox_noblk, etc. is to use -x which is a bit
clumbsy.

Add a --boards option to allow individual build targets to be specified.

 Buildman lets you build all boards, or a subset. Specify the subset by passing
 command-line arguments that list the desired board name, architecture name,
 SOC name, or anything else in the boards.cfg file. Multiple arguments are

 It is convenient to use the -n option to see what will be built based on
 the subset given. Use -v as well to get an actual list of boards.
