This reverts commit 9b0da3f223.
The sigio.c is clearly user space code which is handled by
arch/um/scripts/Makefile.rules (see USER_OBJS rule).
The above mentioned commit simply broke this agreement,
we may not use Linux kernel internal headers in them without
thorough thinking.
Hence, revert the wrong commit.
