Bug Description

Snappy fails to build on arm64 right now . This makes arm64 image builds fail because there is no ubuntu-snappy-cli to install.

It fails because of: "*** Test killed with Quit: ran too long (10m0s)."

Here is the build failure:

I tested this on an amr64 box and I see in:
"""
                _, err := syscall.Sendfile(int(fout.Fd()), int(fin.Fd()), &offset, int(count))
"""
that the offset when set to "2" is not advanced but it remains at "2" (which violates
what the man-page says). So this loops forever.

This appears to be a bug in the upstream gccgo-5 source, I will look into it.

This should fix it, I'm doing a test build of the gccgo-5 package right now but it takes a very long time to build.

Note, libseccomp does not currently have arm64 support so ubuntu-core-launcher will not compile. Obviously, this does not affect this bug but wanted to make sure this was understood.

Silly me, the previous version was on the right track but I overlooked that offset was not initialized at all. This version fixes that now and that makes the cp_linux_test.go work on my box now.
