[common] do not crash when don't have permissions to /tmp/eden directory due to unforessen circumstances (FreeBSD) (#3912)

instead of throwing, use std::error_code and such

due to reasons unberknownst to me, the UID of the /tmp/eden directory was set for another user, this inevitably caused a crash due to wrong permissions (which is a very user unfriendly thing to do generally)
