Make sure the most common IPPROTO_* constants are always available.

These are well known numbers so it should not be a problem to
hardcode values when no constant is provided by the C library.
Ref <http://www.iana.org/assignments/protocol-numbers>.

On some old glibc systems (eg Redhat 6) IPPROTO_TCP is an enum only
and this change workaround that problem as well.
