[PATCH] kbuild: remove duplicate -I flag in addtree

[matt mooney <mfm@muteddisk.com>]

When O= is used, any -I flag given that is not an absolute path gets
duplicated. The $(1) appended to the conditional clause covers the
absolute case, but due to being outside of the conditional statement
it gets added everytime.
