[PATCH v2 11/15] KVM: selftests: Auto generate default tests for KVM Selftests Runner

[Vipin Sharma]

Add logic in Makefile.kvm to auto generate default test files for KVM
Selftests Runner. Preserve the hierarchy of test executables for
autogenerated files.

Autogeneration of default test files guards against missing these files
for new tests cases or rename of existing ones. These autogenerated
files will be checked in so that during git-diff one can easily identify
if the existing test files for the same test binary also needs an
update. It also add new tests automatically in the default coverage.

These files will be auto generated with each make invocation but
overhead should be very small as these are very small files and won't
be shown in git-diff unless test name changes.
