build: Simplify for string.h and getopt.h.

Browse Source 
* configure.ac (AC_CHECK_HEADERS): Remove string.h and getopt.h.
* dirmngr/ks-engine-ldap.c: Remove including getopt.h.
* tools/make-dns-cert.c: Likewise.

--

Checking string.h is supported by AC_HEADER_STDC.  Use of getopt.h
is only needed for getopt_long of GNU extention.
