LOG: [hurd] Fix accessing f_type field of statvfs (#71851)

f4719c4d2cda ("Add support for GNU Hurd in Path.inc and other places")
made llvm use an internal __f_type name for the f_type field (which it
is not supposed to since accessing double-underscore names is explicitly
not supported by standards). In glibc 2.39 this field was renamed to
f_type so application can now access the field as the standard says.

Removed:
