Remove bundled ff14b; use lib-fatfs

Switch to the external lib-fatfs package and remove the bundled FatFs sources. Updated Includes.mk to reference ../lib-fatfs for USB_HOST_MSC, and simplified lib-hal/Rules.mk by removing the FATFS detection block that added ff14b and posix to EXTRA_SRCDIR (and the extra posix include). Deleted the ff14b tree (license, readme, history and source files) and lib-hal/posix/file.cpp to avoid shipping a duplicate/embedded FatFs implementation and rely on the shared lib-fatfs instead.
