[Buildroot] [RFC, PATCH 2/8] package/dropbear: Add separate configuration options for client and server

[Jeremy Kerr <jk@ozlabs.org>]

Currently, the dropbear package installs both client and server
components. For example, this means that when we only want the
client binaries, we also get the server run from init.

Even though it's a multi-call binary (the client and server
exist in the same executable), we'd like to selectively install the
links and init scripts. This change introduces separate configuration
options (both 'default y') for the client and server bits.
