Remove libgomp from dependencies

I've backported a couple of commits from tarantool 3.0 to fix a nasty build problem on Arch Linux / Fedora / any other distro which doesn't provide static libgomp or doesn't build its libgomp with -fPIE (position-independent code). This completely eliminates the need to link against libgomp, statically or dynamically.
