crypto: flip priority of backends to prefer gcrypt
Originally we preferred to use nettle over gcrypt because
gnutls already links to nettle and thus it minimizes the
dependencies. In retrospect this was the wrong criteria to
optimize for.
Currently shipping versions of gcrypt have cipher impls that
are massively faster than those in nettle and this is way
more important. The nettle library is also not capable of
enforcing FIPS compliance, since it considers that out of
scope. It merely aims to provide general purpose impls of
algorithms, and usage policy is left upto the layer above,
such as GNUTLS.
