  strcasecmp() was initially declared in string.h and subsequently moved
to strings.h. For historical reasons it still exists in string.h, but
would require _DEFAULT_SOURCE to be defined.

Due to the above, just include strings.h as currently dictated by the
manpage.

Fixes the following warning:

keying-material-exporter-demo/keyingmaterialexporter.c:155:14: warning: implicit declaration of function  strncasecmp’; did you mean ‘strncmp’? [-Wimplicit-function-declaration]
  155 |         if (!strncasecmp(objbuf, "CN", 2))
      |              ^~~~~~~~~~~
      |              strncmp

If we include strings.h, do we still need string.h then?

Yes, because the file also uses strlen() and strncmp() (declared in 
string.h)

FreeBSD manpage confirms that <strings.h> should be used.  Insanity,
but well.

Your patch has been applied to the master and release/2.5 branch (bugfix,
even if not very critical).
