Raise default min number of instructions (#173)

- Raise min instructions default to 1024 instead of 64
- Default value of 64 has demonstrated tendency to slow down real-life
applications
- Improved the memory safety during `omnitrace_finalize()`
- new modifications guarantee that when `tim::manager::instance()` on
main thread is destroyed, omnitrace will finalize before
- Improved some warning w/ roctracer
- Improved the search for `ROCP_METRICS` and
`OMNITRACE_ROCPROFILER_LIBRARY`
- disable printing env by default
- Attempted to improve the sampling shutdown
