kbuild: fix empty ${PYTHON} in scripts/link-vmlinux.sh

The two commits

  d8d2d38275c1 ("kbuild: remove PYTHON variable")
  a8cccdd95473 ("init: lto: ensure initcall ordering")

were applied in the same development cycle, into two different trees.

After they were merged together, this ${PYTHON} expands to an empty
string.

Therefore, ${srctree}/scripts/jobserver-exec is executed directly.
(it has the executable bit set)

This is working but let's fix the code into the intended form.
