libvirt: fixups for glibc 2.27 - with Sun RPC Interfaces removed

With Sun RPC Interfaces removed from libc we need to use an external
provider for rpc. Polling other distros there seems to be consensus to
use libtirpc so we follow this trend.

Unfortunately this should only require the DEPENDS addition to the
recipe but the upstream project has a few flaws in their Makefiles and
configure which we need to work around so we add 2 new patches to
address these to allow for the use of a sysroot and to use the
$XDR_CFLAGS in a few more places.

+Subject: [PATCH] Makefiles: Add more $XDR_CFLAGS as needed
+
+When building with libtirpc instead of libc-xdr the include search
+path needs to be used. In several places this was missing and it was
+only looking in /usr/include and failing.
