Patch for 'skey' package submitted

[Bill Cole]

They 'skey' package is an implementation of the S/Key algorithm derived 
from OpenBSD code over 20 years ago. It has not been built by the 
buildbots for any system after darwin19 because all the modern compilers 
(including Apple Clang called as 'gcc') enforce the C99 ban on implicit 
declarations.

There's a patch attached to the Trac ticket at 
https://trac.macports.org/ticket/69210 which adds the requisite #include 
statements.

Sorry for no pull request, but history tells me that putting one 
together properly takes me (a non-user of git, usually) a solid 10x as 
long as it should and annoys at least one person (me) and maybe a few 
more (actual devs seeing my messed-up PR.)
