Fall back to global I/O size on macOS
The st_blksize value of struct stat represents the optimal block size
for file I/O operations. FUSE for macOS will use this value when
preforming read or write operations on the file. The smaller st_blksize
is the more context switches are required to complete the operation.
Setting st_blksize to 0 results in FUSE for macOS falling back to the
global I/O size, that can be specified through the "-o iosize=..."
mount-time option.
Fixes osxfuse/osxfuse#389 and osxfuse/sshfs#33
