Replace tests for SYSV_SYSTEM_DIR with HAVE_DIRENT_H, set via autoconf

* configure.in: Check for dirent.h

* dired.c, sysdep.c: test HAVE_DIRENT_H instead of SYSV_SYSTEM_DIR

* s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h,
  s/msdos.h, s/usg5-4.h: don't define SYSV_SYSTEM_DIR

* sed2v2.inp (HAVE_DIRENT_H): Edit to 1
