Fix Conan build: include obfs4_cpp sources in package export

The conan create command copies tor_relays sources to an isolated cache
directory where the sibling ../obfs4_cpp path doesn't exist. Replace the
static exports_sources with an export_sources() method that also copies
obfs4_cpp into the export folder, and add a conditional path check in
CMakeLists.txt to find obfs4_cpp in either location.
