[RFC PATCH v3 5/5] Cleanup: grub-mkconfig_lib: remove unused version comparison functions

[Mathieu Desnoyers <mathieu.desnoyers@efficios.com>]

There are no users left of version_find_latest(), version_test_gt(), and
version_test_numeric(). Remove those unused helper functions. Using
those helper functions is what caused the quadratic sorting performance
issues in the first place, so removing them is a net win.
