ssl: call mbedtls_version_get_string() only if available

The function mbedtls_version_get_string()  is only available if
MBEDTLS_VERSION_C is set in the mbedtls configuration. Check this
before calling this function and print the mbedtls version this was
compiled against instead if mbedtls_version_get_string()  is not
available.

This fixes a compile problem when MBEDTLS_VERSION_C is not set.
