fix false negative reported by check_names.py

The PSA_CRYPTO_C is excluded from typo check for the following
false negative report:

```
  > include/mbedtls/check_config.h:329: 'PSA_CRYPTO_C' looks like a typo. It
    was not found in any macros or any enums. If this is not a typo, put //no-
    check-names after it.
    |
329 |  * Note: ECJPAKE_C depends on MD_C || PSA_CRYPTO_C. */
    |                                       ^^^^^^^^^^^^

```
