Add upstream patch to workaround some combinations of xfsprogs & linux
headers so we don't have to worry about stable breakage anymore. This
fix is already in upstream & unstable versions.

arm/arm64 have some dependencies which are higher than other platforms.
Unfortunately the dependencies are not stable on arm but this package is
so arm updates will come later.

commit ea4d1e1fcc just removed the USE=tls, rather than updating it for
USE=gnutls. Per the description, it has side-effects of enabling
enabling WebSocket & disk quorum features.

The virtfs-proxy-helper program is not a safe binary to give caps.
The following exploit code demonstrates the vulnerability:
~=~=~=~= snip ~=~=~=~=
/* == virtfshell ==
*
* Some distributions make virtfs-proxy-helper from QEMU either SUID or
* give it CAP_CHOWN fs capabilities. This is a terrible idea. While
* virtfs-proxy-helper makes some sort of flimsy check to make sure
* its socket path doesn't already exist, it is vulnerable to TOCTOU.
*
* This should spawn a root shell eventually on vulnerable systems.

Upstream no longer has dedicated configuration options for tls settings.
Instead, it's all run through the gnutls feature test.
We require newer versions of gnutls because supporting older ones gets a
bit messy -- qemu might leverage libgcrypt or nettle depending on how the
gnutls package was built. By forcing the latest version, we can simplify
and only require nettle. This isn't a big deal as it's already stable.
