zephyr: Fix bug where prototype of SNPRINTF was not declared

Fix #10990. A warning is triggered when snprintf is used because it is being declared / configured incorrectly. The MBEDTLS configuration is defaulting to disabling all of LIBC, and then explicitly enabling the LIBC functions in use, this has been done for printf with MBEDTLS_PLATFORM_STD_PRINTF, but not for MBEDTLS_PLATFORM_STD_SNPRINTF.
