kbuild: Fix signing issue for external modules



When running the sign script the kernel is within the source directory
of external modules. This caused issues when the kernel uses relative
paths, like:

make[5]: Entering directory '/build/client/devel/kernel/work/linux-2.6'
make[6]: Entering directory '/build/client/devel/addmodules/vtx/work/vtx'
   INSTALL /build/client/devel/addmodules/vtx/_/lib/modules/6.13.0-devel+/extra/vtx.ko
   SIGN    /build/client/devel/addmodules/vtx/_/lib/modules/6.13.0-devel+/extra/vtx.ko
/bin/sh: 1: scripts/sign-file: not found
   DEPMOD  /build/client/devel/addmodules/vtx/_/lib/modules/6.13.0-devel+

Working around it by using absolute pathes here.
