DAOS-14364 dfuse: Enable faster reading from data cache with dfuse. (#…

…13053)

Allow metadata caching even when the file is open. This was
initially disabled due to conflicts with the interception library
however dfuse now tracks interception library use so it's possible
to only disable when the interception library is in-use rather than
all the time.
