t7527-builtin-fsmonitor was leaking fsmonitor--daemon processes in some
cases.

Accomodate slight difference in the number of events generated on Linux.

On lower-powered systems, spin a little to give the daemon time
to respond to and log filesystem events.

Odd not to quote "$func" here, but anyway...

...uh, we need to wrap "mv"? Why?

Just to get around some quoting issue here?
