Win32: fixed ngx_fs_bsize() for symlinks.

Just a drive letter might not correctly represent file system being used,
notably when using symlinks (as created by "mklink /d"). As such, instead
of calling GetDiskFreeSpace() with just a drive letter, we now always
use GetDiskFreeSpace() with full path.
