Recently reported, the introduction of pmd information exports led to a
breakage of cryptodev unit tests because the test infrastructure relies on the
cryptodev names being available in macros.  This patch fixes the pmd naming to
use the macro names.  Note that the macro names were already pre-stringified,
which won't work as the PMD_REGISTER_DRIVER macro requires the name in both a
processing token and stringified form.  As such the names are defined now as
tokens, and converted where needed to stringified form on demand using RTE_STR.

Tested using the null and aesni_mb crypto pmds, as I don't have hardware for any
other device.  Also not build tested on snow3g or kasumi pmd because building
those requires external libraries that appear to not be open source licensed.
