ci: avoid filling /tmp

[skl]

The offset update workflow is failing, looks like /tmp is full:

2025/10/20 01:47:44 go build returned standard error:
# internal/reflectlite
compile: writing output: write $WORK/b004/_pkg_.a: no space left on device
internal/godebug: mkdir /tmp/go-build1084724249/b065/: no space left on device
# runtime/cgo
_cgo_export.c:13:1: fatal error: error closing ../cct5kKfB.s: No space left on device
   13 | extern char* _cgo_topofstack(void);

compilation terminated.

Closing as the real issue is that the output/cache file for the offsets in the Makefile has been moved from pkg/components to pkg/internal. Great find @mmat11!
