crypto: ecdsa - Migrate to sig_alg backend

A sig_alg backend has just been introduced with the intent of moving all
asymmetric sign/verify algorithms to it one by one.

Migrate ecdsa.c to the new backend.

One benefit of the new API is the use of kernel buffers instead of
sglists, which avoids the overhead of copying signature and digest
sglists back into kernel buffers.  ecdsa.c is thus simplified quite
a bit.
