Switch to lib-fatfs include; remove FATFS build flags

Point USB_HOST_MSC include to ../lib-fatfs instead of ../lib-hal/ff14b/source and remove the FATFS detection/conditional source additions from lib-hal/Rules.mk. The removed logic previously added ff14b/source and posix to EXTRA_SRCDIR when FATFS was enabled; posix is also removed from the default EXTRA_SRCDIR. This simplifies FATFS integration by centralizing headers in lib-fatfs and cleans up obsolete build-flag handling in lib-hal.
