dev-libs/openssl: add Fedora Hobbled-EC for 1.0.

As resolved in the Foundation Trustees meeting 2017/10/22, and the
Licensing team, Fedora's Hobbled-EC patchset is added for USE=bindist in
OpenSSL 1.0 series.

This provides the subset of Elliptic Curve Cryptography that Fedora &
RedHat believe to be free of patent concerns at this time, and use for
their RPMs.

The patch disables or modifies:
- some Elliptic Curves
- some EC methods
- code that interacts the above

This code passes the upstream testsuite with:
FEATURES=test RESTRICT=bindist USE=test emerge =openssl-1.0.2l-r1

See-Also bdd5c9e7d6a375e99b3ae89afd4517a3a5786df2
Upstream: https://src.fedoraproject.org/cgit/rpms/openssl.git
Bug: https://bugs.gentoo.org/531540
Package-Manager: Portage-2.3.8, Repoman-2.3.3
Signed-off-by: Robin H. Johnson <robbat2@gentoo.org>
