[PATCH 11/17] perf tools: Use machine__set_kernel_mmap instead of map_groups__fixup_end

[Jiri Olsa <jolsa@kernel.org>]

The machine__set_kernel_mmap does the same job as map_groups__fixup_end
when used on kernel maps within machine__create_kernel_maps call.

This way we can also remove map_groups__fixup_end function, because there's
no user to it. Also moving machine__set_kernel_mmap up in code, so we don't
need forward declaration.
