This change strips $abs_srctree of the input file containing the
PNM data in the generated output. The motivation for this change
is Yocto emitting a build warning
WARNING: linux-foo-6.8-r0 do_package_qa: QA Issue:
File /usr/src/debug/linux-foo/6.8-r0/drivers/video/logo/logo_linux_clut224.c
in package linux-foo-src contains reference to TMPDIR
So this change brings us one step closer to make the build result
reproducible independent of the build path.
