Turn on _FS_NORTC: This means we don't have to implement get_fattime()
which simplifies life for now.

Automatically set _FS_READONLY based on CONFIG_FAT_WRITE. This requires
including <config.h> since we reference CONFIG_*.

Set _USE_LFN to enable long filename handling; an essential feature.

Set _FS_RPATH so that paths components "." and ".." are correctly parsed
and handled. This enables paths such as "/extlinux/../foo" to work.

Set _USE_LABEL so that volume labels can be read.
