Subject: preadv/pwritev: fix offset argument type
preadv/pwritev don't provide separate version for 64-bit wide off_t,
and default to 32-bit wide off_t, which results in a mismatch between
declaration and definition for user programs built with
-D_FILE_OFFSET_BITS=64.
Make offset argument of both functions __off64_t.
This fixes test misc/tst-preadvwritev on xtensa.
