    astro/cfitsio: fix build with clang 15
    
    During an exp-run for llvm 15 (see bug 265425), it turned out that
    astro/cfitsio failed to build with clang 15:
    
      drvrnet.c:3887:23: warning: call to undeclared function 'gethostbyname'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
                  hostent = gethostbyname(localhost);
                            ^
      drvrnet.c:3887:21: error: incompatible integer to pointer conversion assigning to 'struct hostent *' from 'int' [-Wint-conversion]
                  hostent = gethostbyname(localhost);
                          ^ ~~~~~~~~~~~~~~~~~~~~~~~~
      1 warning and 1 error generated.
    
    This is because the configure script defines _XOPEN_SOURCE=700, for
    unclear reasons, and this hides the gethostbyname() declaration in
    /usr/include/netdb.h. Fix it by removing the line that adds the define.
