reader: Don't lose anonymous-ness of decl-only classes

Browse Source 
When reading an anonymous declaration-only class from ABIXML
libabigail forgets to set the is-anonymous class.  This leads to
spurious change reports when comparing a binary against its ABIXML
representation.  Fixed thus.

Note that this doesn't yet impact any regression test but is useful
for a coming patch that will make abidw --abidiff to emit an error for
all ABI changes, not just the hard incompatible ones.  Without this
change, that coming patch will make runtestreaddwarf to fail.

	* src/abg-reader.cc (build_class_decl): Set the is-anonymous flag
	when reading a decl-only class.
