Use st_blksize and st_blocks members conditionally

Instead of filtering Windows specifically, the preprocessor macros
HAVE_STRUCT_STAT_ST_BLKSIZE and HAVE_STRUCT_STAT_ST_BLOCKS can be used.

These members are mostly present on all POSIX-based systems except on
Windows these days but this syncs the usage style across the code base.

Additionally, in ext/standard/ftp_fopen_wrapper.c to set
ssb->sb.st_blocks, also ssb->sb.st_blksize is added in the condition.
