linux-mod.eclass: support DEBUG_INFO_{SPLIT,DWARF4} bug #653286

When CONFIG_DEBUG_INFO_SPLIT and/or CONFIG_DEBUG_INFO_DWARF4 are set,
the kernel build system tries to create a null.dwo file in the root of
the kernel source directory. This adds an addpredict to prevent this
from failing due to a sandbox failure.
