Fix way to access the RNG for ECDSA counter-measures

Duplicating the g_rng_function variable in ecc_dsa.c means it's not the same
as set in ecc.c, resulting if no randomisation here. The proper way to access
the RNG function from outside ecc.c is uECC_get_rng(), so use that.

This is a side-port of upstream commit
87d74dd8d64a99aaa188961fe763d0841c5abfef

I've verified that there are no other occurrences (the duplication of
g_rng_function in ecc_dh.c had already been removed earlier when centralising
projective coordinate randomisation to mult_safer()).
