Add test for EC pubkey export/import

Browse Source 
There seems to be an issue with i2d_provided() in i2d_evp.c that causes
us to fail to construct a valid chain of encoders for the "type-specific"
output when it's an EC pubkey.  This test is designed to exercise that
codepath for a variety of curves.
