libnm/crypto: rework endianness detection for crypto_verify_pkcs12()

Browse source 
At other places, we already use __BYTE_ORDER define to detect endianness.
We don't need multiple mechanisms.

Also note that meson did not do the correct thing as AC_C_BIGENDIAN,
so meson + nss + big-endian was possibly broken.
