krb5: Add build plumbing

Add tne necessary Makefiles and header files to facilitate building
MIT KRB5 as part of buildworld. Nothing will build until the
WITH_MITKRB5/MK_MITKRB5 option has been plumbed in Makefile.inc1.

Before any changes to Makefile.inc1 are made to enable MIT KRB5,
additional commits to other affected software will need to be committed.

krb5/Makefile was inspired by kerberos5/Makefile. The Makefiles in
krb5/util and krb5/lib were inspired by those in lib/libc and in
lib/ncurses.
