Underscore character may cause bpf prog/map naming collision. For example, x.o with map y_z and x_y.o with map z both result in x_y_z prog/map name, which should be prevented during compile-time. aosp/2147825 will prohibit underscore character in bpf source name (source name derives the obj name). Existing bpf modules with underscore characters in source name need to be updated accordingly.
