Revert "python3-ctypes: depend on ldconfig only if distro-feature set"

Browse Source 
In oe-core, function ldconfig_postinst_fragment use exist of
/sbin/ldconfig to decide if ldconfig is runned to generate the cache,
and function _run_ldconfig will run ldconfig to generate cache during
generate rootfs.  ldconfig.service is actually not used since we have
generate ld.so.cache during do_rootfs, refer[1][2][3]. ldconfig
dependency is necessary when ldconfig not in DISTRO_FEATURES.

The reverted commit causes regression when ldconfig not in
DISTRO_FEATURES, before, without ldconfig in DISTRO_FEATURES,
ctypes.util.find_library(name) can find the lib if it is installed, now,
since ldconfig is not installed, ctypes.util.find_library(name) cannot
find the lib even if it is installed.

Here is one usecase(gtk+3 lib is installed, ctypes.util.find_library
used to find the lib):
import wx.lib.wxcairo as wxcairo
File "/usr/lib/python3.13/site-packages/wx/lib/wxcairo/{}init{}.py", line 59, in <module>
  from .wx_cairocffi import _ContextFromDC, _FontFaceFromFont
File "/usr/lib/python3.13/site-packages/wx/lib/wxcairo/wx_cairocffi.py", line 189, in <module>
  gdkLib = _findGDKLib()
File "/usr/lib/python3.13/site-packages/wx/lib/wxcairo/wx_cairocffi.py", line 181, in _findGDKLib
  return _findHelper([libname], 'gdk',
                     "Unable to find the GDK shared library")
File "/usr/lib/python3.13/site-packages/wx/lib/wxcairo/wx_cairocffi.py", line 170, in _findHelper
  raise RuntimeError(msg)
RuntimeError: Unable to find the GDK shared library
