The test_kexec_jump program builds correctly when invoked from the top-level selftests/Makefile, which explicitly sets the OUTPUT variable. However, building directly in tools/testing/selftests/kexec fails with:

make: *** No rule to make target '/test_kexec_jump', needed by 'test_kexec_jump.sh'. Stop.

This failure occurs because the Makefile rule relies on $(OUTPUT), which is undefined in direct builds.

Fix this by listing test_kexec_jump in TEST_GEN_PROGS, the standard way to declare generated test binaries in the kselftest framework. This ensures the binary is built regardless of invocation context and properly removed by make clean.

Also add the binary to .gitignore to avoid tracking it in version control.
