selinux: Build policy on systems not supporting DCCP protocol
Commit 3895fbbe0cf2ec52d6b6eda66084b6e9f8d88fb2 ("selinux: Add support
for portcon dccp protocol") added support for the (portcon dccp ..)
statement. This fix will allow policy to be built on platforms
(see [1]) that do not have DCCP support by defining the IANA
assigned IP Protocol Number 33 to IPPROTO_DCCP.
