Increase MAX_FILELOCKS for highly parallel IO test

When running hundreds of threads and collecting CLAT, SLAT, IOS on a
per-thread basis, FIO can need a lot of file locks to complete.  When
it can't get them, it gives the cryptic error message:
> fio: filelock.c:182: __fio_lock_file: Assertion `!trylock' failed.

Bump the maximum from 128 to 1024 to give headroom for high core count,
high thread count testing.
