e2fsprogs: fix build on OS X systems

On OS X systems, the compilation of e2fsprogs fails at subst.c due to a
missing sys/stat.h include:

    subst.c:333:14: error: variable has incomplete type 'struct stat'
            struct stat stbuf;
                        ^
    subst.c:333:9: note: forward declaration of 'struct stat'
            struct stat stbuf;
                   ^
    subst.c:392:8: warning: implicit declaration of function 'fstat' is invalid in C99
          [-Wimplicit-function-declaration]
                            if (fstat(fd, &stbuf) == 0) {
                                ^
    subst.c:438:12: warning: implicit declaration of function 'fchmod' is invalid in C99
          [-Wimplicit-function-declaration]
                                    (void) fchmod(ofd, 0444);
                                           ^
    2 warnings and 1 error generated.
    make[3]: *** [subst.o] Error 1

Declare the nescessary HAVE_SYS_STAT_H macro to include the required header in
order to avoid the undeclared stat structure.
