recipes-extended: add master image for testing purposes

Add a custom recipe with custom initramfs and installers, that makes
it easy to deploy a master image for testing purposes.
We need a master image running on the target hardware, that should be a
known good build, with a set of utilities installed so that we use it
to deploy the images under test.

This core-image-testmaster recipe isn't a requirement per se, any image can
be used as long as the required conditions are met.
The test code assumes:
 - that the device has a second rootfs labeled as testrootfs
 - it has a properly configured bootloader entry (called test) for the second kernel and rootfs
 - the master image has a /etc/masterimage file so it can differentiate between master
and test images
 - the master image has tar, mount, bash (basically the normal linux utilities not the busybox
ones)
