module.bbclass: allow to override location of Module.symvers
Requiring all build systems for external kernel modules to place Module.symvers directly into ${B}/. is quite an artificial assumption/requirement. It doesn't have to end up there, but could easily end up somewhere below ${B}. Allow to override the location below ${B} Note that we still don't make use of multiple Module.symvers in case there are any generated by one single kernel module build, but this is no change in behaviour from before and could be added if there really is a demand for that.
