Discovery failures now fall back to the plain end-of-file extension.
Sparse-marking and EOF failures still map to errors.
An IAT-patched regression covers the three truncate paths.

ftruncate, truncate and sceKernelFtruncate extended a file through _chsize_s,
which writes the whole new length as zero bytes. FreeBSD extends the file
without writing data (kern_ftruncate -> ffs_truncate) and fails a length the
file system cannot hold with EFBIG. NativeFtruncate now sets the end of file
with SetFileInformationByHandle and maps ERROR_DISK_FULL to ENOSPC and
ERROR_FILE_TOO_LARGE/ERROR_INVALID_PARAMETER to EFBIG.
