keyingmaterialexporter.c: include strings.h

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
