Do not run benchmarks on linux, we can’t collect anything anyway (#415)

`swift-nio` reusable workflow for running benchmarks has been recently
fixed and now linux benchmarks are failing because we do not have any
thresholds recorded. The main purpose for `swift-log` benchmarks is to
keep track of the amount of instructions and on linux runners
performance metrics are not available, so we cannot check the relevant
metric. Let's remove them.
