dropbear: added 0.47

Note from upstream author about 0.47 and fix for older:
 This release also fixes a potential security issue, which may allow
 authenticated users to run arbitrary code as the server user. I'm unsure
 exactly how likely it is to be exploitable, but anyone who's running a
 multi-user server is advised to upgrade.
