v2: fix test, do not use /dev/null since it client will lock it
- Uses a small assembly file to include binary resources, rather than
objcopy
- Updates `base/common/getResource.cpp` for this new method of inclusion
- Removes linux-only guards in CMake files, as this solution is
cross-platform.
The resulting binary resources are available in the ClickHouse server
binary on Linux, macOS, and illumos platforms. FreeBSD has not been
tested, but will likely work as well.
