nand_util: drop trailing all-0xff pages if requested
Add a flag to nand_read_skip_bad() such that if true, any trailing
pages in an eraseblock whose contents are entirely 0xff will be
dropped.
The implementation is via a new drop_ffs() function which is
based on the function of the same name from the ubiformat
utility by Artem Bityutskiy.
This is as-per the reccomendations of the UBI FAQ [1]
