Add upstream patches for riscv64 architecture support.

These two patches are upstream already.  A third patch is also
upstream, but it is not needed with the older RPM we have, so I didn't
include it.

+Subject: [PATCH 2/3] rpmrc: Convert uname.machine == "riscv" to
+ "riscv32"/"riscv64"/"riscv128".
+
+On RISC-V, the kernel can return uname.machine == "riscv" (for all bit
+sizes).  I say "can" return, because that is the default, but it is
+also possible to compile the kernel specially so it returns "riscv64"
+etc.
+
+GNU is using "riscv64".
+
+This commit converts the kernel uname machine type "riscv" to a more
+suitable value.
+
+This conversion is supposed to be done by the arch_canon table.
+However the arch_canon table is not populated until after the
+defaultMachine function is called for the first time, making it a bit
+useless.  In any case, arch_canon cannot take into account the bit
+size of the architecture, but the C code here can.
