[PATCH] kbuild: move tags from ARCH and include/ ahead of drivers

[Don Mullis <dwm@meer.net>]

Move tags extracted from the ARCH and include/ sub-trees ahead of
those from device drivers, so that the former will appear first
during searches. 

Saves user time during interactive searches for certain patterns
that happen to find unwanted matches in driver files.

Example in emacs:
	 "M-x find-tag PAGE_SIZE"
	 "M-1 M-." (repeated until definition from asm-i386/page.h appears)

Signed-off-by: Don Mullis <dwm@meer.net>

Tested with emacs/etags/ctags v22.0.92 by:
 1) running `make TAGS`, `make tags` with and without patch (ARCH=i386).
 2) verifying improved behavior of tag definition searching with
   "M-x find-tag PAGE_SIZE", "M-1 M-." in emacs
