[kvm-unit-tests PATCH v2 14/18] run_tests: Add KVMTOOL environment variable for kvmtool binary path

[Alexandru Elisei]

kvmtool is often used for prototyping new features, and a developer might
not want to install it system-wide. Add a KVMTOOL environment variable to
make it easier for tests to use a binary not in $PATH.
