Clear board_info entry after waiting for process

When certain DAP tests are run in a certain order, dejagnu will throw
an exception during shutdown.  After adding many logging statements, I
tracked this down to kill_wait_spawned_process not clearing the
'fileid' board_info entry, causing dejagnu to try to wait for the
process a second time -- and fail.

Tom de Vries then pointed out a second instance of this, which I
tracked down to the same problem occurring when spawning gdbserver.

This version of the patch fixes this by adding a new proc that can be
used to clean up board_info after waiting for a process to exit.  I'm
not sure why this problem hasn't affected the test suite in the past.
