[PATCH] x86/vdso: shrink vdso/extable.i via IWYU

[Tanzir Hasan]

This diff uses an open source tool include-what-you-use (IWYU) to modify
the include list, changing indirect includes to direct includes. IWYU is
implemented using the IWYUScripts github repository which is a tool that
is currently undergoing development. These changes seek to improve build
times.

This change to vdso/extable.c resulted in a preprocessed size of
vdso/extable.i from 64332 lines to 45377 lines (-27%) for the x86
defconfig.
