libmd: Add version 1.0.4

[Description][1]:

> This library provides message digest functions found on BSD systems
> either on their libc (NetBSD, OpenBSD) or libmd (FreeBSD, DragonflyBSD,
> macOS, Solaris) libraries and lacking on others like GNU systems.

Needed for dpkg-dev:

    checking for md5.h... no
    configure: error: in `/scratch/local2/dpkg':
    configure: error: md5 digest functions not found

From `config.log`:

    configure:20712: checking md5.h usability
    configure:20712: gcc -c -g -O2  conftest.c >&5
    conftest.c:72:10: fatal error: md5.h: No such file or directory
       72 | #include <md5.h>
          |          ^~~~~~~
    compilation terminated.
