Improve normalization performance for 32bit

- Uses a similar approach to the latest 64bit _normalize.
- Add one useful optimization back into the 64bit _normalize too.

Performance of 'bench' improved by around 0.5% for the 32bit field (but tested on a 64-bit machine).

build: grab full paths to host tools

This ensures that make will work even if PATH has changed, which is often the
case when cross-compiling.

Fixes cross-compiled builds when integrated into Bitcoin's repo.
travis: minimize the dependencies available for each build config

This is a more realistic representation of a build environment. Helps to ensure
configure logic and that headers aren't accidentally assumed to be present.

fix unsigned warning in num_gmp_impl.h
Try to not leave secret data on the stack or heap.

This makes a basic effort and has not been audited.
Doesn't appear to have a measurable performance impact on bench.

It also adds a secp256k1_num_free to secp256k1_ecdsa_pubkey_create.
