gtfs: Remove the EOF optimization

Turns out this is wrong for directories (and often device files).  The
ufs server reports a directory size of 4096, which is what Linux tells
it.  We'd read 4096 bytes worth of records, and then stop.

The 9p man page says:

	 The length records the number of bytes in the file. Directories
	 and most files representing devices have a conventional length
	 of 0.

Instead of mucking around, we'll just issue the RPC for whatever offset
we're asked for.
