[Qemu-devel] [PATCH v2] Makefile: Fix "make clean"

[Fam Zheng <famz@redhat.com>]

This fixes a dangerous bug: "make clean" after "make distclean" will
delete every single file including those under .git, if you do in-tree
build!

Rationale: A first "make distclean" will unset $(DSOSUF), a following
"make distclean" or "make clean" will find all the files and delete it.

Fix it by explicitly typing the file extensions here, and combine
multiple find invocations into one.
