linuxloader/image-prelink/image-mklibs: Fix non-standard path prelinking

Browse Source 
Prelinking on x86-64 wasn't working out the box as it uses /lib and
not /lib64 for libs. Prelink was refusing to link as the dynamic loader
didn't match its idea of the right path. Passing in the --dyanmic-linker
option avoids this.

We can share code from image-mklibs so abstract that into a new class,
linuxloader.bbclass.

This does break prelinking of multilib images, I've opened a bug so we
can loop back and fix that problem, the code would need to iterate the
dynamic loaders (and setup ld.so.conf files for it).

(From OE-Core rev: 7c3f2f61536cc8e0322087558cdcfe29ee2fac6d)
