headers: Drop two #included headers from <linux/interrupt.h> It seems that <linux/interrupt.h> does not need <linux/linkage.h> nor <linux/preempt.h>. 8 kernels builds are successful without these 2 headers (allmodconfig, allyesconfig, allnoconfig, and tinyconfig on both i386 and x86_64). <linux/interrupt.h> is #included 3875 times in 4.16-rc1, so this reduces #include processing of these 2 files by a total of 7750 times. Since I only tested x86 builds, this needs to be tested on other $ARCHes as well.
