Subject: [PATCH] [meshcop] fix compilation error mbedtls_base64_encode not
 defined (#9206)

Fix compilation error mbedtls_base64_encode not defined when compiling
with MBEDTLS_KEY_EXCHANGE_ECDHE_ECDSA_ENABLED disabled.

The logic for including the mbedtls/base64.h header file is doing the
wrong define check.
