[meta-virtualization] [PATCH] containerd: use the target toolchain to build cgo components

[Mark Asselstine]

We need to ensure we are using the target toolchain and sysroot to
avoid possible host contamination, and in the case of non x86-64
target builds, allow the build to complete successfully.

Build tested with qemuarm, intel-corei7-64 and qemux86-64, runtime
tested with qemuarm and qemux86-64 (with the changes from Jason which
he will be sending out shortly).
