package/pahole: fix build with host-cmake 4.0

Browse Source 
host-pahole build fails with recent host-cmake versions, producing the
following error:

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version
of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to
tell
  CMake that the project does not need compatibility with older
versions.

The issue can be reproduced with a minimal defconfig:
  BR2_arm=y
  BR2_cortex_a7=y
  BR2_TOOLCHAIN_EXTERNAL=y
  BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
  BR2_LINUX_KERNEL=y
  BR2_LINUX_KERNEL_DEFCONFIG="versatile"
  BR2_LINUX_KERNEL_NEEDS_HOST_PAHOLE=y
And host-cmake >= 4.0.0

The issue has already been fixed in the upstream pahole project and is
included in versions >= 1.28.

Fix the issue on the current LTS branch by bringing the fixing commit
from upstream.
