[WIP PATCH 11/30] scripts: modify uses of $(srctree) to assume trailing slash

[Elliott Mitchell <ehem+linux@m5p.com>]

This isn't much more than `find | sed` to adjust all uses of $(srctree).
This is split into a separate commit to highlight the actual changes to
the build machinery.

Include the instance of $(objtree) in include/uapi/Makefile while at it.

`grep` was also used to locate things which needed other actions
(notably the non-toplevel Makefile adjustments), but this is roughly:

find . -name Kbuild\* -print0 | xargs -0 sed -i -e's,$(srctree)$,$(srctree:%/=%),' -e's,$(srctree)\([^,/]\),$(srctree:%/=%)\1,g' -es',$(srctree)/,$(srctree),g'

There could be goofs in here or missed bits.  I hope not, but...
