lib/oofatfs: Update oofatfs library to R0.13c working branch.

From https://github.com/micropython/oofatfs, branch work-R0.13c,
commit cb05c9486d3b48ffd6bd7542d8dbbab4b1caf790.

Large code pages (932, 936, 949, 950) have been removed from ffunicode.c
because they were not included in previous versions here.
