build: fix ldconfig executable error in python

build: fix ldconfig executable error in python

The empty executable is causing problems with meson builds, due to the
error: OSError: [Errno 8] Exec format error: 'ldconfig'

This patch changes the empty ldconfig stub to symlink to /bin/true to
work around this issue.

Fixes: FS#4117
