[PATCH] Fix compile when disabling SHA-1

[Peter Krefting]

Fixes compile when disabling SHA-1 with

   #define DROPBEAR_SHA1_HMAC 0
   #define DROPBEAR_RSA_SHA1 0
   #define DROPBEAR_DH_GROUP14_SHA1 0

while keeping SHA-256 enabled.

Should also fix the opposite, but that is not a recommended
configuration.
