Remove uses of mmap() from open.cpp

(These are relatively easy to deal with; just replace them with an
lseek()/read() pair.  Of course, now we're destructively modifying the
fd position; I'd have liked to use pread() but, surprise, that's not
available on mingw.)

       goto error; \
     } \
   }

+  { if(lseek(fd, offset, SEEK_SET) == (off_t) -1) \

 static inline int audiodb_sync_header(adb_t *adb) {
   off_t pos;
   pos = lseek(adb->fd, (off_t) 0, SEEK_CUR);
   if(pos == (off_t) -1) {
     goto error;
