checkpatch: try to catch missing VMLINUX_SYMBOL() in vmlinux.lds.h



Seems like every other release we have someone who updates vmlinux.lds.h
and adds C-visible symbols without VMLINUX_SYMBOL() around them.  So start
checking the file and reject assignments which have plain symbols on
either side.
