benchmark: make temp file path configurable
Browse files Browse the repository at this point in the history
In three fs benchmarks, a temp file is created in the source tree. For
tests, allow the location to be configurable so it gets written to the
test temp directory instead.

Additionally, shave about a second off the test running time by setting
`dur` to `0.1` instead of `1`.
