meta-tizen: privacy-manager-server: Prevent running ldconfig if not on system

Without this change,
bitbake tries to run ldconfig on host instead
and then complains (but not fail !) about permission issue like :

   /sbin/ldconfig.real: \
   Can't create temporary cache file /etc/ld.so.cache~: \
   Permission denied

Note, "or condition" is prefered because of shell's -e option.
