test/keymgmt_internal_test.c: New test of keymgmt internals

This tests diverse internal KEYMGMT features.  The current existing
test checks that evp_keymgmt_export_to_provider() passes the key data
correctly through two instances of the default provider, and that the
resulting numbers at the end match the initial numbers.
