Fix positional I/O support for largefiles

Browse Source 
Commit 335ccb40 introduced positional I/O support for the fileserver,
but didn't handle the largefile versions of preadv and pwritev. As a
result, the fileserver cannot handle files of more than 2Gb in size.

Fix this by using preadv64 and pwritev64 where O_LARGEFILE is defined,
in the same way as for all other I/O primitives.
