mkfs.jffs2: Set mkfs.jffs2 page size runtime instead of fixed
This patch reads the default PAGE_SIZE from sysconf(), i.e. the system mkfs.jffs2 is running on, instead of just setting it to 4096 (which of course is valid for most systems but not all). This is useful if mkfs.jffs2 is running on the target system, e.g. to create a backup image during firmware upgrade, so that the page size does not have to be set explicitly using a command line parameter. The --pagesize option is supported just as before. If the user has not set the page size explicitly with --pagesize, and the system page size is anything other than 4096, warn the user that an unusual page size is being used, since this behavior is different from before.
