x86/build/vdso: Remove unused vdso-syms.lds
This file contains symbol values, and was originally linked into
vmlinux, but I have no idea what it was actually used for.
Since the following commit:
827880ec260b ("x86/um: thin archives build fix")
it is not even linked. Now it is completely orphan, and no problem has
been reported. It is a proof that this file was not needed in the
first place.
