Hello, hello! 🎉 First the disclaimer (I guess it may be relevant): I work at @DataDog on profiling for the [ddtrace](https://github.com/DataDog/dd-trace-rb) gem, although we don't use `rb_profile_frames` (but it is quite interesting). I noticed that the fix for tmm1#122 in tmm1#163 actually missed the new `_POSIX_MONOTONIC_CLOCK` branch, where the math was still incorrect (used 1000 instead of 1000000 when attempting to convert seconds to microseconds). cc @djudd @casperisfine

This is pretty much a rebase of #122, so credits to @benbuckman.
Following #161, most platform use the
clock_gettimeversion of the code, so are not affected, but still worth fixing I guess.@tenderlove
