DHCP client's hooks create /run/dhcpc directory

This directory contains the working files for updating network-related files (like resolv.conf for name servers) before they are copied to the fixed location. Although already in use previously, this location (/var/run/dhcpc or /var/run/dhcpcd) was statically defined on the system.

With the introduction of /run and systems having /var/run -> /run, this is now a dynamically created directory by dhcpc_t. Hence, the policy is enhanced allowing dhcpc_t to create dhcpc_var_run_t directories, and include a file transition for directories created in the var_run_t location(s).

Changes since v1
----------------
- Use create_dirs_pattern instead of manage_dirs_pattern
