sys-libs/libcap-ng: add patches for gnome-keyring-daemon breakage

The upstream author of libcap-ng is ALSO the Fedora packager, and ships
a critical behavior fix regarding new error codes for the recent
versions, both of which are available in different Fedora releases.
After careful review, include BOTH of those releases in our tree, to
allow testing for regressions.

Closes: https://bugs.gentoo.org/759550
