objtool/klp: Add test for rejecting module-owned static branch keys
A static branch key belonging to a module cannot be reached with a klp
relocation: the patch may be applied after that module's static branch init
has run, which corrupts the code. Emitting one anyway produces a module
which loads and then BUG()s the first time the key changes state, so klp
diff has to refuse it.
The fixture differs from the accepted case only in the module name recorded
in .modinfo.
