[meta][PATCH 04/06] kernel-devsrc: strip riscv vdso-cfi-offsets .cmd file

[bruce.ashfield@gmail.com]

From: Bruce Ashfield <bruce.ashfield@gmail.com>

The riscv vDSO gained a CFI-instrumented build (VDSO_CFI_BUILD): when
enabled, arch/riscv/kernel/vdso/Makefile emits the offsets header as
include/generated/vdso-cfi-offsets.h instead of vdso-offsets.h. The
associated kbuild .cmd file records the full compiler invocation and
leaks TMPDIR / the build-host HOME into both the kernel-devsrc and
linux-headers packages, failing do_package_qa on qemuriscv64:

  QA Issue: File .../include/generated/.vdso-cfi-offsets.h.cmd in package
  kernel-devsrc contains reference to TMPDIR [buildpaths]

Remove it alongside the existing vdso*-offsets .cmd files. linux-headers
copies $kerneldir/build/* after this step, so dropping the build-tree
copy clears both packages. riscv-only today and a no-op (rm -f)
elsewhere, so it is safe for all architectures.
