[PATCH kvm-unit-tests] cscope: fix database generation

[Bandan Das <bsd@redhat.com>]

The cscope.files that we generate doesn't include all
source files that are potentially interesting. We should
include all $(ARCH)es  and not the just the one configure
finds. Moreover, $(ARCH) expands to x86_64 which is not the
correct path for x86 sources. Generate cscope.files by searching
for all files starting from root.

While we are there, remove the unnecessary sed substitution
and modify find to include a few other file name extensions.
