crypto/evp/evp_key.c: #define BUFSIZ if <stdio.h> doesn't #define it

CLA: trivial

Fixes #8904

Commit 48feaceb53fa ("Remove the possibility to disable the UI module
entirely", 2017-07-03) made the BUFSIZ references in "evp_key.c"
unconditional, by deleting the preprocessing directive "#ifndef
OPENSSL_NO_UI". This breaks the build when compiling OpenSSL for edk2
(OPENSSL_SYS_UEFI), because edk2's <stdio.h> doesn't #define BUFSIZ.

Provide a fallback definition, like we do in "crypto/ui/ui_util.c" (from
commit 984d6c605216, "Fix no-stdio build", 2015-09-29).
