Make EC_POINT_set_compressed_coordinates_GFp use BIGNUM directly.

All the messing around with field_mul and field_sqr does the same thing
as calling EC_GROUP_get_curve_GFp. This is in preparation for ultimately
moving the field elements to an EC_FELEM type.

Where we draw the BIGNUM / EC_FELEM line determines what EC_FELEM
operations we need. Since we don't care much about the performance of
this function, leave it in BIGNUM so we don't need an EC_FELEM
BN_mod_sqrt just yet. We can push it down later if we feel so inclined.
