cmake: Detect backtrace() support on platforms such as FreeBSD

On FreeBSD use of backtrace requires linking libexecinfo. The current
check_symbol_exists() will fail due to that missing library. Fortunately,
CMake ships with a FindBacktrace module (at least since 3.0) that can
be used to correctly handle platforms such as FreeBSD (and OpenBSD
according to the FindBacktrace source).
