project-lakitu: Add stpcpy to dump-capture-kernel

This change is needed for the dump-capture-kernel to compile after our
next cros_sdk upstream merge.

This change is also needed for the 5.4 kernel, but we already picked up
the change through a stable kernel merge. So there is no action we need
to take for that.

BUG=b/174685352
TEST=emerge-lakitu dump-capture-kernel, and check logging output to make
sure patch is applied. Also run a presubmit
RELEASE_NOTE=None
