[refpolicy] [ hddtemp patch 1/1] hddtemp fixes.

[domg472@gmail.com (Dominick Grift)]

Clean up network control section.
Implement hddtemp_etc_t for /etc/sysconfig/hddtemp. The advantages are:
- hddtemp_t no longer needs access to read all generic etc_t files.
- allows us to implement a meaningful hddtemp_admin()
