Fix tinyipa build uname, picking up hosts kernel

During the tinyipa build process we use the tinyipa package manager,
tce-load. When tce-load trys to look for packages that are kernel specfic
it uses uname to calculate the kernel version, and because we're
building in a chroot it detects the hosts kernel version instead of the
kernel version we are actually going to be using for the final tinyipa
image, this causes it to fail to find certain packages. This patch
injects a fake uname script into the tinyipa build and finalise
environments to simulate running under the correct kernel version.
