When there is a ".." in the source object path, kpatch-gcc can't handle
it correctly. kpatch-gcc is called for objects which were recompiled
and writes the changed objects to "changed_objs". But if the path of the
input obj is something like:
arch/x86/kvm/../../../virt/kvm/.tmp_kvm_main.o
then it will fall into the "*.*.o" branch of the kpatch-gcc case
statement and kpatch-build will report "ERROR: no changed objects
found."
Use Joe's suggestion to revert d526805619 ("kpatch-gcc: update
ignorelist to avoid foo/.lib_exports.o files") and instead add a
"*/.lib_exports.o" pattern.
Fixes #735.
