  Update Edwards and Montgomery key storage length

This commit is a stripped down reimplementation of
72125917695362de3306ebfeb06ce518b6fc42e6, which updated the
expected field_size instead of only the internal storage length.

This broke pkcs11-tool at least with the following modules:
 - libsofthsm2.so
 - libykcs11.so.2
 - opensc-pkcs11.so

The returned error was:
P:5669; T:0x139760863991616 09:18:11.899 [opensc-pkcs11] pkcs15-sec.c:221:format_senv: Card does not support EDDSA with field_size 256
