[PATCH] lkdtm: Fix targets for objcopy usage

[Kees Cook]

The targets for lkdtm's objcopy were missing which caused them to always
be rebuilt. This corrects the problem.

Additionally, commit f8fa70f392fa ("arm64: localise Image objcopy flags")
has landed now, so this removes the work-around for the global OBJCOPY
flag setting.
