test_transfer_receive and test_transfer_send fail on ppc64le architecture

[solopasha]

Describe the bug
test_transfer_receive and test_transfer_send tests fail on ppc64le architecture.

To Reproduce
Steps to reproduce the behavior:

1. try building kitty 0.30.0 on ppc64le.
2. See error

Unfortunately I dont have access to this architecture so its not really
possible for me to debug. If you do have access to it you might get more
useful errors by running the transfer kitten on it

kitten transfer some-file /tmp/som-file
and
kitten transfer --transmit-deltas some-file /tmp/some-file

I don't have it, I tried in the qemu emulator and got:

[root@ba9da8ff7ccd test]# kitten transfer 1 /tmp/test12-file
Scanning files…
Found 1 files and directories, requesting transfer permission…
Error: function not implemented

which comes somewhere from golang.org/x/sys...

Hmm well I have no clue how one would go about debugging that short of sticking print statements everywhere to see which go system function is failing. Is there a ready made qemu img I can use to test so I dont have to waste time building one
