dropbear: update to 2014.63

Upstream changelog:
https://matt.ucc.asn.au/dropbear/CHANGES

This adds elliptic curve cryptography (ECC) support as an option, disabled
by default.

dropbear mips 34kc uClibc binary size:
before: 161,672 bytes
after, without ECC (default): 164,968
after, with ECC: 198,008

Signed-off-by: Catalin Patulea <cat@vv.carleton.ca>

+               authentication.

+               Key exchange algorithms:
+                 ecdh-sha2-nistp256
+                 ecdh-sha2-nistp384

+                 ecdsa-sha2-nistp521
+
+               Does not generate ECC host keys by default (ECC key exchange will not be used,
+               only ECC public key auth).
+
+               Increases binary size by about 36 kB (MIPS).
