gccrs: dump: Fix spacing with dots and references

A space was output around dots as well as after references, this made
things kinda horrible to look at and clearly not usual.

gcc/rust/ChangeLog:

	* ast/rust-ast-dump.cc (Dump::require_spacing): Add a rule to
	remove spaces around dots and after references.
