Make template_symbol derive from symbol

Browse source 
This changes template_symbol to derive from symbol, which seems a bit
cleaner; and also more consistent with rust_vtable_symbol.

2017-11-17  Tom Tromey  <tom@tromey.com>

	* dwarf2read.c (read_func_scope): Update.
	* symtab.h (struct template_symbol): Derive from symbol.
	<base>: Remove.
