docs: move README to README.md and symlink

This allows a slightly nicer formatting of the text when displayed on
some repository hosts. We keep a symlink from README for the
old-school purists.

-description of this project, as well as running tests and adding
-tests HOWTOs.
-
-This directory contains sources for a kvm test suite.
-
-To create the test images do
-  ./configure
-  make
-in this directory. Test images are created in ./<ARCH>/*.flat
-
-Then use the runner script to detect the correct invocation and
-invoke the test, e.g.
-  ./x86-run ./x86/msr.flat
-or
-  ./run_tests.sh
-to run them all.
-
-To select a specific qemu binary, specify the QEMU=<path>
-environment variable, e.g.
-  QEMU=/tmp/qemu/x86_64-softmmu/qemu-system-x86_64 ./x86-run ./x86/msr.flat
-
-To create and use standalone tests do
-  ./configure
-  make standalone
-  (send tests/some-test somewhere)
-  (go to somewhere)
-  ./some-test
-
-'make install' will install all tests in PREFIX/share/kvm-unit-tests/tests,
-each as a standalone test.

-./scripts:	helper scripts for building and running tests
-./lib:		general architecture neutral services for the tests
-./lib/<ARCH>:	architecture dependent services for the tests
