Unit test function for mbedtls_ecp_muladd

Write a simple unit test for mbedtls_ecp_muladd().

Add just one pair of test cases. One of them causes the argument to
fix_negative to have an argument with an all-bits-zero least
significant limb which briefly triggered a branch in Mbed TLS 2.26+.
See https://github.com/ARMmbed/mbedtls/issues/4296 and
https://github.com/ARMmbed/mbedtls/pull/4297.
